# Alterlab Infographics

> Creates professional infographics with Nano Banana Pro AI and smart iterative refinement, using Gemini 3 Pro for automated quality review and an optional Perplexity Sonar research phase for accurate, sourced data — supports 10 infographic types, 8 industry styles, and colorblind-safe palettes. Use when the request is for an infographic, data-story graphic, statistical poster, comparison chart, timeline, process/how-to visual, or list/social graphic that pairs a designed layout with figures. Use alterlab-scientific-schematics instead for technical flowcharts, CONSORT/PRISMA, pathways, or architecture diagrams; alterlab-generate-image for non-infographic illustrations. Part of the AlterLab Academic Skills suite.

# 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 |

## 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

## Quick Start

Generate any infographic by describing it; the script handles generation, review, and iteration.

```bash
# Generate a list infographic (default threshold 7.5/10)
python scripts/generate_infographic.py \
  "5 benefits of regular exercise" \
  -o figures/exercise_benefits.png --type list

# Marketing (highest threshold: 8.5/10)
python scripts/generate_infographic.py \
  "Product features comparison" \
  -o figures/product_comparison.png --type comparison --doc-type marketing

# Corporate style + colorblind-safe palette
python scripts/generate_infographic.py \
  "Company milestones 2010-2025" \
  -o figures/timeline.png --type timeline --style corporate

# WITH RESEARCH for accurate, up-to-date data
python 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 the initial infographic
3. **Review 1**: **Gemini 3 Pro** evaluates quality against the document-type threshold
4. **Decision**: quality >= threshold → **DONE** (early stop); below threshold → improve prompt and regenerate
5. **Repeat** until quality meets threshold OR max iterations reached

**Output**: Versioned images plus a detailed JSON review log with quality scores, critiques, and early-stop info.

## Core Workflow

1. **Pick the type** (`--type`) — one of 10 presets (statistical, timeline, process, comparison, list, geographic, hierarchical, anatomical, resume, social). Full catalog with examples in `references/type_catalog.md`.
2. **Pick a style and (optionally) palette** — 8 industry `--style` presets, 3 colorblind-safe `--palette` presets. Tables in `references/type_catalog.md`.
3. **Set `--doc-type`** to choose the quality threshold (see table above).
4. **Add `--research`** when accurate sourced data matters.
5. **Configure the API key** (`OPENROUTER_API_KEY`) and run; review the JSON log and regenerate with a more specific prompt if needed.

## Configuration

Set the OpenRouter API key (read from the environment):

```bash
export OPENROUTER_API_KEY='your_api_key_here'   # https://openrouter.ai/keys
```

**Data & privacy:** prompts and research/infographic content are sent to a third-party API (OpenRouter) for generation and quality review. Avoid sending confidential, clinical, or unpublished material.
