Infographics

Simply describe what you want, and Nano Banana Pro creates it.

Quick Start

Generate any infographic by simply describing it:

# 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.

# 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

better sleep, lower blood pressure, emotional balance"

✗ Avoid vague prompts:

"meditation infographic"

Include Data Points

✓ Good:

"Market growth from $10B (2020) to $45B (2025), CAGR 35%"

✗ Vague:

"market is growing"

Specify Visual Elements

✓ Good:

"Timeline showing 5 milestones with icons for each event"

Troubleshooting

Common Issues

Problem: Text in infographic is unreadable

• Solution: Reduce text content; use --type to specify layout type

Problem: Colors clash or are inaccessible

• Solution: Use --palette wong for colorblind-safe colors

Problem: Quality score too low

• Solution: Increase iterations with --iterations 3; use more specific prompt

Problem: Wrong infographic type generated

• Solution: Always specify --type flag for consistent results
