# Infographics
## Overview
Infographics are visual representations of information, data, or knowledge designed to present complex content quickly and clearly. **This skill uses Nano Banana Pro AI for infographic generation with Gemini 3 Pro quality review and Perplexity Sonar for research.**
**How it works:**
- (Optional) **Research phase**: Gather accurate facts and statistics using Perplexity Sonar
- Describe your infographic in natural language
- Nano Banana Pro generates publication-quality infographics automatically
- **Gemini 3 Pro reviews quality** against document-type thresholds
- **Smart iteration**: Only regenerates if quality is below threshold
- Professional-ready output in minutes
- No design skills required
**Quality Thresholds by Document Type:**
| Document Type | Threshold | Description |
|---------------|-----------|-------------|
| marketing | 8.5/10 | Marketing materials - must be compelling |
| report | 8.0/10 | Business reports - professional quality |
| presentation | 7.5/10 | Slides, talks - clear and engaging |
| social | 7.0/10 | Social media content |
| internal | 7.0/10 | Internal use |
| draft | 6.5/10 | Working drafts |
| default | 7.5/10 | General purpose |
**Simply describe what you want, and Nano Banana Pro creates it.**
## Quick Start
Generate any infographic by simply describing it:
```bash
# Generate a list infographic (default threshold 7.5/10)
python skills/infographics/scripts/generate_infographic.py \
"5 benefits of regular exercise" \
-o figures/exercise_benefits.png --type list
# Generate for marketing (highest threshold: 8.5/10)
python skills/infographics/scripts/generate_infographic.py \
"Product features comparison" \
-o figures/product_comparison.png --type comparison --doc-type marketing
# Generate with corporate style
python skills/infographics/scripts/generate_infographic.py \
"Company milestones 2010-2025" \
-o figures/timeline.png --type timeline --style corporate
# Generate with colorblind-safe palette
python skills/infographics/scripts/generate_infographic.py \
"Heart disease statistics worldwide" \
-o figures/health_stats.png --type statistical --palette wong
# Generate WITH RESEARCH for accurate, up-to-date data
python skills/infographics/scripts/generate_infographic.py \
"Global AI market size and growth projections" \
-o figures/ai_market.png --type statistical --research
```
**What happens behind the scenes:**
1. **(Optional) Research**: Perplexity Sonar gathers accurate facts, statistics, and data
2. **Generation 1**: Nano Banana Pro creates initial infographic following design best practices
3. **Review 1**: **Gemini 3 Pro** evaluates quality against document-type threshold
4. **Decision**: If quality >= threshold → **DONE** (no more iterations needed!)
5. **If below threshold**: Improved prompt based on critique, regenerate
6. **Repeat**: Until quality meets threshold OR max iterations reached
**Smart Iteration Benefits:**
- ✅ Saves API calls if first generation is good enough
- ✅ Higher quality standards for marketing materials
- ✅ Faster turnaround for drafts/internal use
- ✅ Appropriate quality for each use case
**Output**: Versioned images plus a detailed review log with quality scores, critiques, and early-stop information.
## When to Use This Skill
Use the **infographics** skill when:
- Presenting data or statistics in a visual format
- Creating timeline visualizations for project milestones or history
- Explaining processes, workflows, or step-by-step guides
- Comparing options, products, or concepts side-by-side
- Summarizing key points in an engaging visual format
- Creating geographic or map-based data visualizations
- Building hierarchical or organizational charts
- Designing social media content or marketing materials
**Use scientific-schematics instead for:**
- Technical flowcharts and circuit diagrams
- Biological pathways and molecular diagrams
- Neural network architecture diagrams
- CONSORT/PRISMA methodology diagrams
---
## Research Integration
### Automatic Data Gathering (`--research`)
When creating infographics that require accurate, up-to-date data, use the `--research` flag to automatically gather facts and statistics using **Perplexity Sonar Pro**.
```bash
# Research and generate statistical infographic
python skills/infographics/scripts/generate_infographic.py \
"Global renewable energy adoption rates by country" \
-o figures/renewable_energy.png --type statistical --research
# Research for timeline infographic
python skills/infographics/scripts/generate_infographic.py \
"History of artificial intelligence breakthroughs" \
-o figures/ai_history.png --type timeline --research
# Research for comparison infographic
python skills/infographics/scripts/generate_infographic.py \
"Electric vehicles vs hydrogen vehicles comparison" \
-o figures/ev_hydrogen.png --type comparison --research
```
### What Research Provides
The research phase automatically:
1. **Gathers Key Facts**: 5-8 relevant facts and statistics about the topic
2. **Provides Context**: Background information for accurate representation
3. **Finds Data Points**: Specific numbers, percentages, and dates
4. **Cites Sources**: Mentions major studies or sources
5. **Prioritizes Recency**: Focuses on 2023-2026 information
### When to Use Research
**Enable research (`--research`) for:**
- Statistical infographics requiring accurate numbers
- Market data, industry statistics, or trends
- Scientific or medical information
- Current events or recent developments
- Any topic where accuracy is critical
**Skip research for:**
- Simple conceptual infographics
- Internal process documentation
- Topics where you provide all the data in the prompt
- Speed-critical generation
### Research Output
When research is enabled, additional files are created:
- `{name}_research.json` - Raw research data and sources
- Research content is automatically incorporated into the infographic prompt

# Infographic Design Principles
This reference covers the fundamental design principles for creating effective, professional infographics.
---
## Visual Hierarchy
Visual hierarchy guides the viewer's eye through your infographic in a deliberate order, ensuring key information is seen first.
### The Hierarchy Pyramid
1. **Primary Elements** (Seen First)
- Headlines and titles
- Large numbers or key statistics
- Hero images or main illustrations
- Call-to-action elements
2. **Secondary Elements** (Seen Second)
- Subheadings and section titles
- Charts and graphs
- Icons and visual markers
- Key supporting text
3. **Tertiary Elements** (Seen Last)
- Body text and descriptions
- Legends and labels
- Source citations
- Fine print and footnotes
### Creating Hierarchy
**Size**: Larger elements attract attention first
- Headlines: 200-300% larger than body text
- Key stats: Make numbers 2-4x larger than labels
- Important icons: 1.5-2x larger than supporting icons
**Color**: Bright and contrasting colors draw the eye
- Use accent colors sparingly for emphasis
- Reserve the brightest color for the most important element
- Use muted colors for supporting information
**Position**: Top-left and center are seen first
- Place most important content at top or center
- Supporting details toward bottom or edges
- Reading flow: top-to-bottom, left-to-right (in Western cultures)
**Contrast**: High contrast elements stand out
- Dark on light or light on dark for key text
- Colored elements against neutral backgrounds
- Borders and shadows to lift key elements
**White Space**: Isolation draws attention
- Surround important elements with space
- Don't crowd key information
- Use spacing to group related items

## The 60-40 Rule
The optimal infographic balances visual and text content:
- **60% Visual Elements**: Icons, charts, illustrations, images, shapes
- **40% Text Content**: Headlines, labels, descriptions, data
### Why This Matters
- Too much text: Feels like a document, not an infographic
- Too many visuals: Lacks substance and clarity
- Right balance: Engaging AND informative
### Applying the Rule
**Visual Elements (60%)**
- Charts and graphs
- Icons and symbols
- Illustrations
- Photos
- Decorative shapes
- Color blocks
- Lines and connectors
**Text Elements (40%)**
- Headlines and titles
- Subheadings
- Data labels
- Brief descriptions
- Source citations
- Calls to action
---
## White Space (Negative Space)
White space is the empty area between and around elements. It's not wasted space—it's a design tool.
### Functions of White Space
1. **Improves Readability**: Gives eyes rest between content
2. **Creates Focus**: Isolated elements attract attention
3. **Groups Content**: Related items appear connected
4. **Adds Elegance**: Premium feel to design
5. **Reduces Clutter**: Prevents overwhelming viewers
### White Space Guidelines
**Margins**: Space around the entire infographic
- Minimum 5-10% of width/height
- More margin = more premium feel
- Consistent on all sides
**Padding**: Space inside elements (boxes, cards)
- Minimum equal to text line height
- More padding for important elements
- Consistent within similar elements
**Gaps**: Space between elements
- Related items: Small gaps (8-16px)
- Unrelated items: Large gaps (24-48px)
- Sections: Largest gaps (48-72px)
**Line Spacing**: Space between lines of text
- Body text: 1.4-1.6x font size
- Headlines: 1.1-1.3x font size
- Lists: 1.5-2x font size
---
## Typography
### Font Selection
**Sans-Serif Fonts** (Recommended for Infographics)
- Clean, modern appearance
- Better screen readability
- Professional feel
- Examples: Arial, Helvetica, Open Sans, Roboto, Montserrat
**Serif Fonts** (Use Sparingly)
- Traditional, authoritative feel
- Good for headlines in formal contexts
- Examples: Georgia, Times New Roman, Playfair Display
**Display Fonts** (Headlines Only)
- High impact for titles
- NOT for body text
- Examples: Impact, Bebas Neue, Oswald
### Font Pairing Rules
1. **Maximum 2-3 fonts** per infographic
2. **Contrast is key**: Pair different styles (serif + sans-serif)
3. **Establish roles**: One for headlines, one for body, one for accents
4. **Maintain consistency**: Same font for same purpose throughout
**Safe Pairings:**
- Montserrat (headlines) + Open Sans (body)
- Playfair Display (headlines) + Roboto (body)
- Bebas Neue (headlines) + Lato (body)
- Oswald (headlines) + Source Sans Pro (body)
### Font Sizes
| Element | Size Range | Weight |
|---------|------------|--------|
| Main Title | 36-72pt | Bold |
| Section Headers | 24-36pt | Bold/Semi-bold |
| Subheadings | 18-24pt | Semi-bold |
| Body Text | 12-16pt | Regular |
| Captions/Labels | 10-14pt | Regular/Light |
| Fine Print | 8-10pt | Light |
### Typography Best Practices
1. **Left-align body text** (easier to read than centered)
2. **Center-align headlines** (for impact)
3. **Limit line length** to 45-75 characters
4. **Use bold sparingly** for emphasis
5. **Avoid all caps** for body text (hard to read)
6. **ALL CAPS acceptable** for short headlines/labels
7. **Maintain contrast** between text and background (4.5:1 minimum)
---
## Story Structure
Every effective infographic tells a story with three parts:
### 1. Introduction (Hook)
**Purpose**: Grab attention, establish topic
**Elements:**
- Compelling headline
- Eye-catching hero visual
- Key statistic or question
- Topic introduction
**Best Practices:**
- Make it impossible to ignore
- Promise value ("Learn how to...")
- Create curiosity
- 10-15% of total space
### 2. Body (Content)
**Purpose**: Deliver the main information
**Elements:**
- Data and statistics
- Step-by-step content
- Comparisons and analysis
- Supporting visuals
**Best Practices:**
- Logical flow (chronological, importance, or categorical)
- Clear section breaks
- Balance visuals and text
- 70-80% of total space
### 3. Conclusion (Takeaway)
**Purpose**: Summarize, call to action
**Elements:**
- Key takeaway or summary
- Call to action
- Source citations
- Branding/attribution
**Best Practices:**
- Reinforce main message
- Clear next step for viewer
- Don't introduce new information
- 10-15% of total space
---
## Alignment and Grids
### Grid Systems
Use invisible grids to align elements consistently:
**Column Grid** (Most Common)
- 2, 3, 4, or 6 columns
- Elements span one or more columns
- Gutters (gaps) between columns
- Creates orderly, professional look
**Modular Grid**
- Columns + rows = modules
- More flexibility for varied content
- Good for complex layouts
- Dashboard-style designs
### Alignment Types
**Left Alignment**
- Most common for text
- Creates strong left edge
- Easy to scan
- Professional appearance
**Center Alignment**
- Good for headlines
- Creates symmetry
- Use sparingly for text
- Works for single elements
**Right Alignment**
- Rarely used for primary content
- Good for numbers in tables
- Can feel unusual in Western design
- Use intentionally
### Alignment Best Practices
1. **Pick one primary alignment** and stick to it
2. **Align related elements** to the same edge or center
3. **Use invisible grid lines** for consistency
4. **Avoid random placement**—everything should align to something
5. **Create visual connections** through alignment
---
## Color Usage
### Color Functions in Infographics
1. **Establish hierarchy**: Bright colors for important items
2. **Group related items**: Same color = same category
3. **Create contrast**: Distinguish between elements
4. **Evoke emotions**: Colors carry psychological meaning
5. **Reinforce brand**: Consistent with brand identity
### Color Distribution
**60-30-10 Rule:**
- **60%** Dominant color (background, large areas)
- **30%** Secondary color (supporting elements)
- **10%** Accent color (highlights, CTAs)
### Color Psychology
| Color | Association | Best For |
|-------|-------------|----------|
| Blue | Trust, professionalism, calm | Corporate, tech, healthcare |
| Green | Growth, nature, money | Environmental, finance, health |
| Red | Urgency, energy, passion | Alerts, sales, food |
| Orange | Friendly, confident, creative | CTAs, youth brands |
| Yellow | Optimism, caution, attention | Highlights, warnings |
| Purple | Luxury, creativity, wisdom | Premium brands, education |
| Black | Sophistication, power, elegance | Luxury, formal |
| White | Clean, simple, space | Backgrounds, breathing room |
### Contrast Requirements
For accessibility (WCAG 2.1 AA):
- **Normal text**: 4.5:1 contrast ratio minimum
- **Large text** (18pt+): 3:1 contrast ratio minimum
- **Graphics and UI**: 3:1 contrast ratio minimum
Tools to check contrast:
- WebAIM Contrast Checker
- Coolors Contrast Checker
- Adobe Color Accessibility Tools
---
## Icon Usage
### Icon Styles
**Line Icons** (Outline)
- Clean, modern look
- Work well at small sizes
- Best for minimal designs
- Consistent line weight important
**Filled Icons** (Solid)
- Bolder visual impact
- Good for quick recognition
- Work well as focal points
- More accessible at small sizes
**Illustrated Icons**
- More personality and uniqueness
- Higher visual weight
- Best for playful designs
- May not scale well
### Icon Best Practices
1. **Use one style consistently** throughout the infographic
2. **Ensure recognizability**—icons should be immediately understood
3. **Maintain consistent size** for icons at the same hierarchy level
4. **Add labels** when icon meaning isn't 100% clear
5. **Match visual weight** of icons to surrounding elements
6. **Consider color** carefully—single color often cleaner
7. **Avoid icon overload**—not everything needs an icon
### Icon Size Guidelines
| Context | Recommended Size |
|---------|------------------|
| Hero/Feature icon | 64-128px |
| Section icon | 32-48px |
| List item icon | 24-32px |
| Inline icon | 16-24px |
---
## Data Visualization Best Practices
### Choosing Chart Types
| Data Type | Best Chart |
|-----------|------------|
| Comparison (few items) | Bar chart |
| Comparison (many items) | Horizontal bar |
| Parts of a whole | Pie/donut chart |
| Trend over time | Line chart |
| Distribution | Histogram |
| Relationship | Scatter plot |
| Geographic | Map/choropleth |
| Hierarchy | Treemap |
| Flow/process | Sankey diagram |
### Chart Best Practices
1. **Label everything**: Axes, data points, legends
2. **Start Y-axis at zero** for bar charts (avoid misleading)
3. **Limit pie slices** to 5-7 maximum
4. **Use consistent colors** for same categories across charts
5. **Remove chart junk**: No 3D effects, minimal gridlines
6. **Highlight key data**: Use color to emphasize important points
### Number Presentation
- **Large numbers**: Use abbreviations (1.2M, not 1,200,000)
- **Percentages**: Include % symbol, one decimal max
- **Comparisons**: Use consistent units and precision
- **Context**: Always provide reference points ("2x industry average")
---
## Accessibility Considerations
### Visual Accessibility
1. **Color alone shouldn't convey meaning**
- Add patterns, labels, or shapes
- Works for colorblind users
2. **Sufficient contrast**
- 4.5:1 for normal text
- 3:1 for large text and graphics
3. **Text size**
- Minimum 10pt for print
- Minimum 12px for digital
4. **Don't rely on color legends**
- Label data directly when possible
### Colorblind-Safe Design
- Use colorblind-safe palettes (see color_palettes.md)
- Test with colorblindness simulators
- Add patterns or textures for differentiation
- Use labels and direct annotation
### Reading Accessibility
- Clear hierarchy and flow
- Concise text
- Simple language
- Adequate spacing
- Logical reading order

# LaTeX Research Posters # LaTeX Research Posters
@@ -25,41 +22,548 @@ This skill should be used when:
- Building posters with complex multi-column layouts - Building posters with complex multi-column layouts
- Integrating figures, tables, equations, and citations in poster format - Integrating figures, tables, equations, and citations in poster format
## Visual Enhancement with Scientific Schematics ## AI-Powered Visual Element Generation
**⚠️ MANDATORY: Every research poster MUST include at least 2-3 AI-generated figures using the scientific-schematics skill.** **STANDARD WORKFLOW: Generate ALL major visual elements using AI before creating the LaTeX poster.**
This is not optional. Posters are primarily visual media - text-heavy posters fail to communicate effectively. Before finalizing any poster: This is the recommended approach for creating visually compelling posters:
1. Generate at minimum TWO schematics or diagrams 1. Plan all visual elements needed (title, intro, methods, results, conclusions)
2. Target 3-4 figures for comprehensive posters (methodology flowchart, key results visualization, conceptual framework) 2. Generate each element using scientific-schematics or Nano Banana Pro
3. Figures should occupy 40-50% of poster area 3. Assemble generated images in the LaTeX template
4. Add text content around the visuals
**How to generate figures:** **Target: 60-70% of poster area should be AI-generated visuals, 30-40% text.**
- Use the **scientific-schematics** skill to generate AI-powered publication-quality diagrams
- Simply describe your desired diagram in natural language
- Nano Banana Pro will automatically generate, review, and refine the schematic
**How to generate schematics:** ---
```bash
python scripts/generate_schematic.py "your diagram description" -o figures/output.png ### CRITICAL: Preventing Content Overflow
**⚠️ POSTERS MUST NOT HAVE TEXT OR CONTENT CUT OFF AT EDGES.**
**Common Overflow Problems:**
1. **Title/footer text extending beyond page boundaries**
2. **Too many sections crammed into available space**
3. **Figures placed too close to edges**
4. **Text blocks exceeding column widths**
**Prevention Rules:**
**1. Limit Content Sections (MAXIMUM 5-6 sections for A0):**
```
✅ GOOD - 5 sections with room to breathe:
- Title/Header
- Introduction/Problem
- Methods
- Results (1-2 key findings)
- Conclusions
❌ BAD - 8+ sections crammed together:
- Overview, Introduction, Background, Methods,
- Results 1, Results 2, Discussion, Conclusions, Future Work
``` ```
The AI will automatically: **2. Set Safe Margins in LaTeX:**
- Create publication-quality images with proper formatting ```latex
- Review and refine through multiple iterations % tikzposter - add generous margins
- Ensure accessibility (colorblind-friendly, high contrast) \documentclass[25pt, a0paper, portrait, margin=25mm]{tikzposter}
- Save outputs in the figures/ directory
**When to add schematics:** % baposter - ensure content doesn't touch edges
- Research methodology flowcharts for poster content \begin{poster}{
- Conceptual framework diagrams columns=3,
- Experimental design visualizations colspacing=2em, % Space between columns
- Data analysis pipeline diagrams headerheight=0.1\textheight, % Smaller header
- System architecture diagrams % Leave space at bottom
- Biological pathway illustrations }
- Any complex concept that benefits from visualization ```
For detailed guidance on creating schematics, refer to the scientific-schematics skill documentation. **3. Figure Sizing - Never 100% Width:**
```latex
% Leave margins around figures
\includegraphics[width=0.85\linewidth]{figure.png} % NOT 1.0\linewidth
```
**4. Check for Overflow Before Printing:**
```bash
# Compile and check PDF at 100% zoom
pdflatex poster.tex
# Look for:
# - Text cut off at any edge
# - Content touching page boundaries
# - Overfull hbox warnings in .log file
grep -i "overfull" poster.log
```
**5. Word Count Limits:**
- **A0 poster**: 300-800 words MAXIMUM
- **Per section**: 50-100 words maximum
- **If you have more content**: Cut it or make a handout
---
### CRITICAL: Poster-Size Font Requirements
**⚠️ ALL text within AI-generated visualizations MUST be poster-readable.**
When generating graphics for posters, you MUST include font size specifications in EVERY prompt. Poster graphics are viewed from 4-6 feet away, so text must be LARGE.
**⚠️ COMMON PROBLEM: Content Overflow and Density**
The #1 issue with AI-generated poster graphics is **TOO MUCH CONTENT**. This causes:
- Text overflow beyond boundaries
- Unreadable small fonts
- Cluttered, overwhelming visuals
- Poor white space usage
**SOLUTION: Generate SIMPLE graphics with MINIMAL content.**
**MANDATORY prompt requirements for EVERY poster graphic:**
```
POSTER FORMAT REQUIREMENTS (STRICTLY ENFORCE):
- ABSOLUTE MAXIMUM 3-4 elements per graphic (3 is ideal)
- ABSOLUTE MAXIMUM 10 words total in the entire graphic
- NO complex workflows with 5+ steps (split into 2-3 simple graphics instead)
- NO multi-level nested diagrams (flatten to single level)
- NO case studies with multiple sub-sections (one key point per case)
- ALL text GIANT BOLD (80pt+ for labels, 120pt+ for key numbers)
- High contrast ONLY (dark on white OR white on dark, NO gradients with text)
- MANDATORY 50% white space minimum (half the graphic should be empty)
- Thick lines only (5px+ minimum), large icons (200px+ minimum)
- ONE SINGLE MESSAGE per graphic (not 3 related messages)
```
**⚠️ BEFORE GENERATING: Review your prompt and count elements**
- If your description has 5+ items → STOP. Split into multiple graphics
- If your workflow has 5+ stages → STOP. Show only 3-4 high-level steps
- If your comparison has 4+ methods → STOP. Show only top 3 or Our vs Best Baseline
**Content limits per graphic type (STRICT):**
| Graphic Type | Max Elements | Max Words | Reject If | Good Example |
|--------------|--------------|-----------|-----------|--------------|
| Flowchart | **3-4 boxes MAX** | **8 words** | 5+ stages, nested steps | "DISCOVER → VALIDATE → APPROVE" (3 words) |
| Key findings | **3 items MAX** | **9 words** | 4+ metrics, paragraphs | "95% ACCURATE" "2X FASTER" "FDA READY" (6 words) |
| Comparison chart | **3 bars MAX** | **6 words** | 4+ methods, legend text | "OURS: 95%" "BEST: 85%" (4 words) |
| Case study | **1 case, 3 elements** | **6 words** | Multiple cases, substories | Logo + "18 MONTHS" + "to discovery" (2 words) |
| Timeline | **3-4 points MAX** | **8 words** | Year-by-year detail | "2020 START" "2022 TRIAL" "2024 APPROVED" (6 words) |
**Example - WRONG (7-stage workflow - TOO COMPLEX):**
```bash
# ❌ BAD - This creates tiny unreadable text like the drug discovery poster
python scripts/generate_schematic.py "Drug discovery workflow showing: Stage 1 Target Identification, Stage 2 Molecular Synthesis, Stage 3 Virtual Screening, Stage 4 AI Lead Optimization, Stage 5 Clinical Trial Design, Stage 6 FDA Approval. Include success metrics, timelines, and validation steps for each stage." -o figures/workflow.png
# Result: 7+ stages with tiny text, unreadable from 6 feet - POSTER FAILURE
```
**Example - CORRECT (simplified to 3 key stages):**
```bash
# ✅ GOOD - Same content, split into ONE simple high-level graphic
python scripts/generate_schematic.py "POSTER FORMAT for A0. ULTRA-SIMPLE 3-box workflow: 'DISCOVER' → 'VALIDATE' → 'APPROVE'. Each word in GIANT bold (120pt+). Thick arrows (10px). 60% white space. NO substeps, NO details. 3 words total. Readable from 10 feet." -o figures/workflow_overview.png
# Result: Clean, impactful, readable - can add detail graphics separately if needed
```
**Example - WRONG (complex case studies with multiple sections):**
```bash
# ❌ BAD - Creates cramped unreadable sections
python scripts/generate_schematic.py "Case studies: Insilico Medicine (drug candidate, discovery time, clinical trials), Recursion Pharma (platform, methodology, results), Exscientia (drug candidates, FDA status, timeline). Include company logos, metrics, and outcomes." -o figures/cases.png
# Result: 3 case studies with 4+ elements each = 12+ total elements, tiny text
```
**Example - CORRECT (one case study, one key metric):**
```bash
# ✅ GOOD - Show ONE case with ONE key number
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case study card: Company logo (large), '18 MONTHS' in GIANT text (150pt), 'to discovery' below (60pt). 3 elements total: logo + number + caption. 50% white space. Readable from 10 feet." -o figures/case_single.png
# Result: Clear, readable, impactful. Make 3 separate graphics if you need 3 cases.
```
**Example - WRONG (key findings too complex):**
```bash
# BAD - too many items, too much detail
python scripts/generate_schematic.py "Key findings showing 8 metrics: accuracy 95%, precision 92%, recall 94%, F1 0.93, AUC 0.97, training time 2.3 hours, inference 50ms, model size 145MB with comparison to 5 baseline methods" -o figures/findings.png
# Result: Cramped graphic with tiny numbers
```
**Example - CORRECT (key findings simple):**
```bash
# GOOD - only 3 key items, giant numbers
python scripts/generate_schematic.py "POSTER FORMAT for A0. KEY FINDINGS with ONLY 3 large cards. Card 1: '95%' in GIANT text (120pt) with 'ACCURACY' below (48pt). Card 2: '2X' in GIANT text with 'FASTER' below. Card 3: checkmark icon with 'VALIDATED' in large text. 50% white space. High contrast colors. NO other text or details." -o figures/findings.png
# Result: Bold, readable impact statement
```
**Font size reference for poster prompts:**
| Element | Minimum Size | Prompt Keywords |
|---------|--------------|-----------------|
| Main numbers/metrics | 72pt+ | "huge", "very large", "giant", "poster-size" |
| Section titles | 60pt+ | "large bold", "prominent" |
| Labels/captions | 36pt+ | "readable from 6 feet", "clear labels" |
| Body text | 24pt+ | "poster-readable", "large text" |
**Always include in prompts:**
- "POSTER FORMAT" or "for A0 poster" or "readable from 6 feet"
- "VERY LARGE TEXT" or "huge bold fonts"
- Specific text that should appear (so it's baked into the image)
- "minimal text, maximum impact"
- "high contrast" for readability
- "generous margins" and "no text near edges"
---
### CRITICAL: AI-Generated Graphic Sizing
**⚠️ Each AI-generated graphic should focus on ONE concept with MINIMAL content.**
**Problem**: Generating complex diagrams with many elements leads to small text.
**Solution**: Generate SIMPLE graphics with FEW elements and LARGE text.
**Example - WRONG (too complex, text will be small):**
```bash
# BAD - too many elements in one graphic
python scripts/generate_schematic.py "Complete ML pipeline showing data collection,
preprocessing with 5 steps, feature engineering with 8 techniques, model training
with hyperparameter tuning, validation with cross-validation, and deployment with
monitoring. Include all labels and descriptions." -o figures/pipeline.png
```
**Example - CORRECT (simple, focused, large text):**
```bash
# GOOD - split into multiple simple graphics with large text
# Graphic 1: High-level overview (3-4 elements max)
python scripts/generate_schematic.py "POSTER FORMAT for A0: Simple 4-step pipeline.
Four large boxes: DATA → PROCESS → MODEL → RESULTS.
GIANT labels (80pt+), thick arrows, lots of white space.
Only 4 words total. Readable from 8 feet." -o figures/overview.png
# Graphic 2: Key result (1 metric highlighted)
python scripts/generate_schematic.py "POSTER FORMAT for A0: Single key metric display.
Giant '95%' text (150pt+) with 'ACCURACY' below (60pt+).
Checkmark icon. Minimal design, high contrast.
Readable from 10 feet." -o figures/accuracy.png
```
**Rules for AI-generated poster graphics:**
| Rule | Limit | Reason |
|------|-------|--------|
| **Elements per graphic** | 3-5 maximum | More elements = smaller text |
| **Words per graphic** | 10-15 maximum | Minimal text = larger fonts |
| **Flowchart steps** | 4-5 maximum | Keeps labels readable |
| **Chart categories** | 3-4 maximum | Prevents crowding |
| **Nested levels** | 1-2 maximum | Avoids complexity |
**Split complex content into multiple simple graphics:**
```
Instead of 1 complex diagram with 12 elements:
→ Create 3 simple diagrams with 4 elements each
→ Each graphic can have LARGER text
→ Arrange in poster with clear visual flow
```
---
### Step 0: MANDATORY Pre-Generation Review (DO THIS FIRST)
**⚠️ BEFORE generating ANY graphics, review your content plan:**
**For EACH planned graphic, ask these questions:**
1. **Element count**: Can I describe this in 3-4 items or less?
- ❌ NO → Simplify or split into multiple graphics
- ✅ YES → Continue
2. **Complexity check**: Is this a multi-stage workflow (5+ steps) or nested diagram?
- ❌ YES → Flatten to 3-4 high-level steps only
- ✅ NO → Continue
3. **Word count**: Can I describe all text in 10 words or less?
- ❌ NO → Cut text, use single-word labels
- ✅ YES → Continue
4. **Message clarity**: Does this graphic convey ONE clear message?
- ❌ NO → Split into multiple focused graphics
- ✅ YES → Continue to generation
**Common patterns that ALWAYS fail (reject these):**
- "Show stages 1 through 7..." → Split into high-level overview (3 stages) + detail graphics
- "Multiple case studies..." → One case per graphic
- "Timeline from 2015 to 2024 with annual milestones..." → Show only 3-4 key years
- "Comparison of 6 methods..." → Show only top 3 or Our method vs Best baseline
- "Architecture with all layers and connections..." → High-level only (3-4 components)
### Step 1: Plan Your Poster Elements
After passing the pre-generation review, identify visual elements needed:
1. **Title Block** - Stylized title with institutional branding (optional - can be LaTeX text)
2. **Introduction Graphic** - Conceptual overview (3 elements max)
3. **Methods Diagram** - High-level workflow (3-4 steps max)
4. **Results Figures** - Key findings (3 metrics max per figure, may need 2-3 separate figures)
5. **Conclusion Graphic** - Summary visual (3 takeaways max)
6. **Supplementary Icons** - Simple icons, QR codes, logos (minimal)
### Step 2: Generate Each Element (After Pre-Generation Review)
**⚠️ CRITICAL: Review Step 0 checklist before proceeding.**
Use the appropriate tool for each element type:
**For Schematics and Diagrams (scientific-schematics):**
```bash
# Create figures directory
mkdir -p figures
# Drug discovery workflow - HIGH-LEVEL ONLY, 3 stages
# BAD: "Stage 1: Target ID, Stage 2: Molecular Synthesis, Stage 3: Virtual Screening, Stage 4: AI Lead Opt..."
# GOOD: Collapse to 3 mega-stages
python scripts/generate_schematic.py "POSTER FORMAT for A0. ULTRA-SIMPLE 3-box workflow: 'DISCOVER' (120pt bold) → 'VALIDATE' (120pt bold) → 'APPROVE' (120pt bold). Thick arrows (10px). 60% white space. ONLY these 3 words. NO substeps. Readable from 12 feet." -o figures/workflow_simple.png
# System architecture - MAXIMUM 3 components
python scripts/generate_schematic.py "POSTER FORMAT for A0. ULTRA-SIMPLE 3-component stack: 'DATA' box (120pt) → 'AI MODEL' box (120pt) → 'PREDICTION' box (120pt). Thick vertical arrows. 60% white space. 3 words only. Readable from 12 feet." -o figures/architecture.png
# Timeline - ONLY 3 key milestones (not year-by-year)
# BAD: "2018, 2019, 2020, 2021, 2022, 2023, 2024 with events"
# GOOD: Only 3 breakthrough moments
python scripts/generate_schematic.py "POSTER FORMAT for A0. Timeline with ONLY 3 points: '2018' + icon, '2021' + icon, '2024' + icon. GIANT years (120pt). Large icons. 60% white space. NO connecting lines or details. Readable from 12 feet." -o figures/timeline.png
# Case study - ONE case, ONE key metric
# BAD: "3 case studies: Insilico (details), Recursion (details), Exscientia (details)"
# GOOD: ONE case with ONE number
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case study: Large logo + '18 MONTHS' (150pt bold) + 'to discovery' (60pt). 3 elements total. 60% white space. Readable from 12 feet." -o figures/case1.png
# If you need 3 cases → make 3 separate simple graphics (not one complex graphic)
```
**For Stylized Blocks and Graphics (Nano Banana Pro):**
```bash
# Title block - SIMPLE
python scripts/generate_schematic.py "POSTER FORMAT for A0. Title block: 'ML FOR DRUG DISCOVERY' in HUGE bold text (120pt+). Dark blue background. ONE subtle icon. NO other text. 40% white space. Readable from 15 feet." -o figures/title_block.png
# Introduction visual - SIMPLE, 3 elements only
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE problem visual with ONLY 3 icons: drug icon, arrow, target icon. ONE label per icon (80pt+). 50% white space. NO detailed text. Readable from 8 feet." -o figures/intro_visual.png
# Conclusion/summary - ONLY 3 items, GIANT numbers
python scripts/generate_schematic.py "POSTER FORMAT for A0. KEY FINDINGS with EXACTLY 3 cards only. Card 1: '95%' (150pt font) with 'ACCURACY' (60pt). Card 2: '2X' (150pt) with 'FASTER' (60pt). Card 3: checkmark icon with 'READY' (60pt). 50% white space. NO other text. Readable from 10 feet." -o figures/conclusions_graphic.png
# Background visual - SIMPLE, 3 icons only
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE visual with ONLY 3 large icons in a row: problem icon → challenge icon → impact icon. ONE word label each (80pt+). 50% white space. NO detailed text. Readable from 8 feet." -o figures/background_visual.png
```
**For Data Visualizations - SIMPLE, 3 bars max:**
```bash
# SIMPLE chart with ONLY 3 bars, GIANT labels
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE bar chart with ONLY 3 bars: BASELINE (70%), EXISTING (85%), OURS (95%). GIANT percentage labels ON the bars (100pt+). NO axis labels, NO legend, NO gridlines. Our bar highlighted in different color. 40% white space. Readable from 8 feet." -o figures/comparison_chart.png
```
### Step 2b: MANDATORY Post-Generation Review (Before Assembly)
**⚠️ CRITICAL: Review EVERY generated graphic before adding to poster.**
**For each generated figure, open at 25% zoom and check:**
1. **✅ PASS criteria (all must be true):**
- Can read ALL text clearly at 25% zoom
- Count elements: 3-4 or fewer
- White space: 50%+ of image is empty
- Simple enough to understand in 2 seconds
- NOT a complex workflow with 5+ stages
- NOT multiple nested sections
2. **❌ FAIL criteria (regenerate if ANY are true):**
- Text is small or hard to read at 25% zoom → REGENERATE with "150pt+" fonts
- More than 4 elements → REGENERATE with "ONLY 3 elements"
- Less than 50% white space → REGENERATE with "60% white space"
- Complex multi-stage workflow → SPLIT into 2-3 simple graphics
- Multiple case studies cramped together → SPLIT into separate graphics
- Takes more than 3 seconds to understand → SIMPLIFY and regenerate
**Common failures and fixes:**
- "7-stage workflow with tiny text" → Regenerate as "3 high-level stages only"
- "3 case studies in one graphic" → Generate 3 separate simple graphics
- "Timeline with 8 years" → Regenerate with "ONLY 3 key milestones"
- "Comparison of 5 methods" → Regenerate with "ONLY Our method vs Best baseline (2 bars)"
**DO NOT PROCEED to assembly if ANY graphic fails the checks above.**
### Step 3: Assemble in LaTeX Template
After all figures pass the post-generation review, include them in your poster template:
**tikzposter example:**
```latex
\documentclass[25pt, a0paper, portrait]{tikzposter}
\begin{document}
\maketitle
\begin{columns}
\column{0.5}
\block{Introduction}{
\centering
\includegraphics[width=0.85\linewidth]{figures/intro_visual.png}
\vspace{0.5em}
Brief context text here (2-3 sentences max).
}
\block{Methods}{
\centering
\includegraphics[width=0.9\linewidth]{figures/methods_flowchart.png}
}
\column{0.5}
\block{Results}{
\begin{minipage}{0.48\linewidth}
\centering
\includegraphics[width=\linewidth]{figures/result_1.png}
\end{minipage}
\hfill
\begin{minipage}{0.48\linewidth}
\centering
\includegraphics[width=\linewidth]{figures/result_2.png}
\end{minipage}
\vspace{0.5em}
Key findings in 3-4 bullet points.
}
\block{Conclusions}{
\centering
\includegraphics[width=0.8\linewidth]{figures/conclusions_graphic.png}
}
\end{columns}
\end{document}
```
**baposter example:**
```latex
\headerbox{Methods}{name=methods,column=0,row=0}{

\includegraphics[width=0.95\linewidth]{figures/methods_flowchart.png}
}
\headerbox{Results}{name=results,column=1,row=0}{

```
### Example: Complete Poster Generation Workflow
**Full workflow with ALL quality checks:**
```bash
# STEP 0: Pre-Generation Review (MANDATORY)
# Content plan: Drug discovery poster
# - Workflow: 7 stages → ❌ TOO MANY → Reduce to 3 mega-stages ✅
# - 3 case studies → ❌ TOO MANY → One case per graphic (make 3 graphics) ✅
# - Timeline 2018-2024 → ❌ TOO DETAILED → Only 3 key years ✅
# STEP 1: Create figures directory
mkdir -p figures
# STEP 2: Generate ULTRA-SIMPLE graphics with strict limits
# Workflow - HIGH-LEVEL ONLY (collapsed from 7 stages to 3)
python scripts/generate_schematic.py "POSTER FORMAT for A0. ULTRA-SIMPLE 3-box workflow: 'DISCOVER' → 'VALIDATE' → 'APPROVE'. Each word 120pt+ bold. Thick arrows (10px). 60% white space. ONLY 3 words total. Readable from 12 feet." -o figures/workflow.png
# Case study 1 - ONE case, ONE metric (will make 3 separate graphics)
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case: Company logo + '18 MONTHS' (150pt bold) + 'to drug discovery' (60pt). 3 elements only. 60% white space. Readable from 12 feet." -o figures/case1.png
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case: Company logo + '95% SUCCESS' (150pt bold) + 'in trials' (60pt). 3 elements only. 60% white space." -o figures/case2.png
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case: Company logo + 'FDA APPROVED' (150pt bold) + '2024' (60pt). 3 elements only. 60% white space." -o figures/case3.png
# Timeline - ONLY 3 key years (not 7 years)
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONLY 3 years: '2018' (150pt) + icon, '2021' (150pt) + icon, '2024' (150pt) + icon. Large icons. 60% white space. NO lines or details. Readable from 12 feet." -o figures/timeline.png
# Results - ONLY 2 bars (our method vs best baseline, not 5 methods)
python scripts/generate_schematic.py "POSTER FORMAT for A0. TWO bars only: 'BASELINE 70%' and 'OURS 95%' (highlighted). GIANT percentages (150pt) ON bars. NO axis, NO legend. 60% white space. Readable from 12 feet." -o figures/results.png
# STEP 2b: Post-Generation Review (MANDATORY)
# Open each figure at 25% zoom:
# ✅ workflow.png: 3 elements, text readable, 60% white - PASS
# ✅ case1.png: 3 elements, giant numbers, clean - PASS
# ✅ case2.png: 3 elements, giant numbers, clean - PASS
# ✅ case3.png: 3 elements, giant numbers, clean - PASS
# ✅ timeline.png: 3 elements, readable, simple - PASS
# ✅ results.png: 2 bars, giant percentages, clear - PASS
# ALL PASS → Proceed to assembly
# STEP 3: Compile LaTeX poster
pdflatex poster.tex
# STEP 4: PDF Overflow Check (see Section 11)
grep "Overfull" poster.log
# Open at 100% and check all 4 edges
```
**If ANY graphic fails Step 2b review:**
- Too many elements → Regenerate with "ONLY 3 elements"
- Small text → Regenerate with "150pt+" or "GIANT BOLD (150pt+)"
- Cluttered → Regenerate with "60% white space" and "ULTRA-SIMPLE"
- Complex workflow → SPLIT into multiple simple 3-element graphics
### Visual Element Guidelines
**⚠️ CRITICAL: Each graphic must have ONE message and MAXIMUM 3-4 elements.**
**ABSOLUTE LIMITS - These are NOT guidelines, these are HARD LIMITS:**
- **MAXIMUM 3-4 elements** per graphic (3 is ideal)
- **MAXIMUM 10 words** total per graphic
- **MINIMUM 50% white space** (60% is better)
- **MINIMUM 120pt** for key numbers/metrics
- **MINIMUM 80pt** for labels
**For each poster section - STRICT requirements:**
| Section | Max Elements | Max Words | Example Prompt (REQUIRED PATTERN) |
|---------|--------------|-----------|-------------------------------------|
| **Introduction** | 3 icons | 6 words | "POSTER FORMAT for A0: ULTRA-SIMPLE 3 icons: [icon1] [icon2] [icon3]. ONE WORD labels (100pt bold). 60% white space. 3 words total." |
| **Methods** | 3 boxes | 6 words | "POSTER FORMAT for A0: ULTRA-SIMPLE 3-box workflow: 'STEP1' → 'STEP2' → 'STEP3'. GIANT labels (120pt+). 60% white space. 3 words only." |
| **Results** | 2-3 bars | 6 words | "POSTER FORMAT for A0: TWO bars: 'BASELINE 70%' 'OURS 95%'. GIANT percentages (150pt+) ON bars. NO axis. 60% white space." |
| **Conclusions** | 3 cards | 9 words | "POSTER FORMAT for A0: THREE cards: '95%' (150pt) 'ACCURATE', '2X' (150pt) 'FASTER', checkmark 'READY'. 60% white space." |
| **Case Study** | 3 elements | 5 words | "POSTER FORMAT for A0: ONE case: logo + '18 MONTHS' (150pt) + 'to discovery' (60pt). 60% white space." |
| **Timeline** | 3 points | 3 words | "POSTER FORMAT for A0: THREE years only: '2018' '2021' '2024' (150pt each). Large icons. 60% white space. NO details." |
**MANDATORY prompt elements (ALL required, NO exceptions):**
1. **"POSTER FORMAT for A0"** - MUST be first
2. **"ULTRA-SIMPLE"** or **"ONLY X elements"** - content limit
3. **"GIANT (120pt+)"** or specific font sizes - readability
4. **"60% white space"** - mandatory breathing room
5. **"readable from 10-12 feet"** - viewing distance
6. **Exact count** of words/elements - "3 words total" or "ONLY 3 icons"
**PATTERNS THAT ALWAYS FAIL (REJECT IMMEDIATELY):**
- ❌ "7-stage drug discovery workflow" → Split to "3 mega-stages"
- ❌ "Timeline from 2015-2024 with annual updates" → "ONLY 3 key years"
- ❌ "3 case studies with details" → Make 3 separate simple graphics
- ❌ "Comparison of 5 methods with metrics" → "ONLY 2: ours vs best"
- ❌ "Complete architecture showing all layers" → "3 components only"
- ❌ "Show stages 1,2,3,4,5,6" → "3 high-level stages"
**PATTERNS THAT WORK:**
- ✅ "3 mega-stages collapsed from 7" → Proper simplification
- ✅ "ONE case with ONE metric" → Will make multiple if needed
- ✅ "ONLY 3 milestones" → Selective, focused
- ✅ "2 bars: ours vs baseline" → Direct comparison
- ✅ "3-component high-level view" → Appropriately simplified

**Step 2: Visual Inspection Checklist** **Step 2: OVERFLOW CHECK (CRITICAL) - DO THIS IMMEDIATELY AFTER COMPILATION**
**⚠️ THIS IS THE #1 CAUSE OF POSTER FAILURES. Check BEFORE proceeding.**
**Step 2a: Check LaTeX Log File**
```bash
# Check for overflow warnings (these are ERRORS, not suggestions)
grep -i "overfull\|underfull\|badbox" poster.log
# ANY "Overfull" warning = content is cut off or extending beyond boundaries
# FIX ALL OF THESE before proceeding
```
**Common overflow warnings and what they mean:**
- `Overfull \hbox (15.2pt too wide)` → Text or graphic is 15.2pt wider than column
- `Overfull \vbox (23.5pt too high)` → Content is 23.5pt taller than available space
- `Badbox` → LaTeX struggling to fit content within boundaries
**Step 2b: Visual Edge Inspection (100% zoom in PDF viewer)**
**Check ALL FOUR EDGES systematically:**
1. **TOP EDGE:**
- [ ] Title completely visible (not cut off)
- [ ] Author names fully visible
- [ ] No graphics touching top margin
- [ ] Header content within safe zone
2. **BOTTOM EDGE:**
- [ ] References fully visible (not cut off)
- [ ] Acknowledgments complete
- [ ] Contact info readable
- [ ] No graphics cut off at bottom
3. **LEFT EDGE:**
- [ ] No text touching left margin
- [ ] All bullet points fully visible
- [ ] Graphics have left margin (not bleeding off)
- [ ] Column content within bounds
4. **RIGHT EDGE:**
- [ ] No text extending beyond right margin
- [ ] Graphics not cut off on right
- [ ] Column content stays within bounds
- [ ] QR codes fully visible
5. **BETWEEN COLUMNS:**
- [ ] Content stays within individual columns
- [ ] No text bleeding into adjacent columns
- [ ] Figures respect column boundaries
**If ANY check fails, you have overflow. FIX IMMEDIATELY before continuing:**
**Fix hierarchy (try in order):**
1. **Check AI-generated graphics first:**
- Are they too complex (5+ elements)? → Regenerate simpler
- Do they have tiny text? → Regenerate with "150pt+" fonts
- Are there too many? → Reduce number of figures
2. **Reduce sections:**
- More than 5-6 sections? → Combine or remove
- Example: Merge "Discussion" into "Conclusions"
3. **Cut text content:**
- More than 800 words total? → Cut to 300-500
- More than 100 words per section? → Cut to 50-80
4. **Adjust figure sizing:**
- Using `width=\linewidth`? → Change to `width=0.85\linewidth`
- Using `width=1.0\columnwidth`? → Change to `width=0.9\columnwidth`
5. **Increase margins (last resort):**
```latex

**CRITICAL: Generate SIMPLE figures with MINIMAL content. Each graphic = ONE message.**
**Content limits:**
- Maximum 4-5 elements per graphic
- Maximum 15 words total per graphic
- 50% white space minimum
- GIANT fonts (80pt+ for labels, 120pt+ for key numbers)

3. **Review generated figures - check for overflow:**
- **View at 25% zoom**: All text still readable?
- **Count elements**: More than 5? → Regenerate simpler
- **Check white space**: Less than 40%? → Add "60% white space" to prompt
- **Font too small?**: Add "EVEN LARGER" or increase pt sizes

## Common Pitfalls to Avoid ## Common Pitfalls to Avoid
**AI-Generated Graphics Mistakes (MOST COMMON):**
- ❌ Too many elements in one graphic (10+ items) → Keep to 3-5 max
- ❌ Text too small in AI graphics → Specify "GIANT (100pt+)" or "HUGE (150pt+)"
- ❌ Too much detail in prompts → Use "SIMPLE" and "ONLY X elements"
- ❌ No white space specification → Add "50% white space" to every prompt
- ❌ Complex flowcharts with 8+ steps → Limit to 4-5 steps maximum
- ❌ Comparison charts with 6+ items → Limit to 3 items maximum
- ❌ Key findings with 5+ metrics → Show only top 3
**Fixing Overflow in AI Graphics:**
If your AI-generated graphics are overflowing or have small text:
1. Add "SIMPLER" or "ONLY 3 elements" to prompt
2. Increase font sizes: "150pt+" instead of "80pt+"
3. Add "60% white space" instead of "50%"
4. Remove sub-details: "NO sub-steps", "NO axis labels", "NO legend"
5. Regenerate with fewer elements

## Paper Quality and Popularity Prioritization
**CRITICAL**: When searching for papers, ALWAYS prioritize high-quality, influential papers over obscure or low-impact publications. Quality matters more than quantity.
### Citation-Based Ranking
Prioritize papers based on citation count relative to their age:
| Paper Age | Citation Threshold | Classification |
|-----------|-------------------|----------------|
| 0-3 years | 20+ citations | Noteworthy |
| 0-3 years | 100+ citations | Highly Influential |
| 3-7 years | 100+ citations | Significant |
| 3-7 years | 500+ citations | Landmark Paper |
| 7+ years | 500+ citations | Seminal Work |
| 7+ years | 1000+ citations | Foundational |
**When reporting citations**: Always indicate approximate citation count when known (e.g., "cited 500+ times" or "highly cited").
### Venue Quality Tiers
Prioritize papers from higher-tier venues:
**Tier 1 - Premier Venues** (Always prefer):
- **General Science**: Nature, Science, Cell, PNAS
- **Medicine**: NEJM, Lancet, JAMA, BMJ
- **Field-Specific Flagships**: Nature Medicine, Nature Biotechnology, Nature Methods, Nature Genetics, Cell Stem Cell, Immunity
- **Top CS/AI**: NeurIPS, ICML, ICLR, ACL, CVPR (for ML/AI topics)
**Tier 2 - High-Impact Specialized** (Strong preference):
- Journals with Impact Factor > 10
- Top conferences in subfields (e.g., EMNLP, NAACL, ECCV, MICCAI)
- Society flagship journals (e.g., Blood, Circulation, Gastroenterology)
**Tier 3 - Respected Specialized** (Include when relevant):
- Journals with Impact Factor 5-10
- Established conferences in the field
- Well-indexed specialized journals
**Tier 4 - Other Peer-Reviewed** (Use sparingly):
- Lower-impact journals, only if directly relevant and no better source exists
### Author Reputation Indicators
Prefer papers from established, reputable researchers:
- **Senior authors with high h-index** (>40 in established fields)
- **Multiple publications in Tier-1 venues**
- **Leadership positions** at recognized research institutions
- **Recognized expertise**: Awards, editorial positions, society fellows
- **First/last author on landmark papers** in the field
### Direct Relevance Scoring
Always prioritize papers that directly address the research question:
1. **Primary Priority**: Papers directly addressing the exact research question
2. **Secondary Priority**: Papers with applicable methods, data, or conceptual frameworks
3. **Tertiary Priority**: Tangentially related papers (include ONLY if from Tier-1 venues or highly cited)
### Practical Application
When conducting research lookups:
1. **Start with the most influential papers** - Look for highly-cited, foundational work first
2. **Prioritize Tier-1 venues** - Nature, Science, Cell family journals, NEJM, Lancet for medical topics
3. **Check author credentials** - Prefer work from established research groups
4. **Balance recency with impact** - Recent highly-cited papers > older obscure papers > recent uncited papers
5. **Report quality indicators** - Include citation counts, journal names, and author affiliations in responses
**Example Quality-Focused Query Response**:
```
Key findings from high-impact literature:
1. Smith et al. (2023), Nature Medicine (IF: 82.9, cited 450+ times)

### Structure ### Format: Flowing Paragraphs (Default)
Most journals now require **structured abstracts** with labeled sections:
**Background/Objective**: Why was the study needed? What was the aim? **⚠️ CRITICAL: Write abstracts as flowing paragraphs, NOT with labeled sections.**
- 1-2 sentences
- State the research problem and objective
**Methods**: How was it done? Most scientific papers use **unstructured abstracts** written as one or two cohesive paragraphs. This is the standard format for the majority of journals including Nature, Science, Cell, PNAS, and most field-specific journals.

study in a 500-bed teaching hospital to evaluate UV-C disinfection added to
standard cleaning protocols. Environmental surfaces were cultured monthly and
infection rates tracked via surveillance data. Post-intervention, surface
contamination decreased by 47% (95% CI: 38-56%, p<0.001), and catheter-associated
urinary tract infections declined from 3.2 to 1.8 per 1000 catheter-days (RR=0.56,
95% CI: 0.38-0.83, p=0.004). No adverse effects were observed. These findings
demonstrate that UV-C disinfection significantly reduces environmental contamination
and infection rates, suggesting it may be a valuable addition to hospital infection
control programs.

### Abstract Structure (as unified paragraph)
While written as flowing prose, the abstract should cover these elements in order:
1. **Context and problem** (1-2 sentences): Why the research matters, what gap exists
2. **Study description** (1-2 sentences): What was done and how (study design, methods)
3. **Key findings** (2-4 sentences): Main results with specific quantitative data
4. **Significance** (1-2 sentences): Interpretation, implications, and conclusions
### Length ### Length
- Typically 100-250 words (check journal requirements) - Typically 150-300 words (check journal requirements)
- Some journals allow up to 300 words - Some journals allow up to 350 words
### Key Rules ### Key Rules
- Write the abstract **last** (after completing all other sections) - Write the abstract **last** (after completing all other sections)
- **Write as flowing paragraph(s)** - no labeled sections
- Make it fully understandable without reading the paper - Make it fully understandable without reading the paper
- Do not cite references in the abstract - Do not cite references in the abstract
- Avoid abbreviations or define them at first use - Avoid abbreviations or define them at first use
- Use past tense for methods and results, present tense for conclusions - Use past tense for methods and results, present tense for conclusions
- Include key quantitative results with statistical measures - Include key quantitative results with statistical measures
- Use transitions to connect sentences naturally
### When to Use Structured Abstracts (Exception)
Only use labeled sections (Background/Objective, Methods, Results, Conclusions) when:
- The journal **explicitly requires** structured abstracts in their author guidelines
- Common in some medical journals (JAMA, BMJ, Annals of Internal Medicine)
- Always check journal requirements before formatting
Even for structured abstracts, write each section as complete sentences, not fragments.
