# Generating Infographics

Generate branded infographics with custom themes and backgrounds using @antv/infographic.

## Prerequisites

1. Run `/brand-init` to create project structure

2. Run `/brand-extract` to generate brand-philosophy.md

3. Run `/template-infographic` to create an infographic template

### No-Brand Safeguard

If `brand-philosophy.md` is not found OR contains no `## Color Palette` section:

- **STOP generation** — inform user: "No brand colors found. Run `/brand-extract` first to analyze your brand."

- If user insists on proceeding: use deliberately bland neutrals (#1a1a1a, #666, #f5f5f5, system fonts)

- Never fall back to any recognizable brand colors

## When to Use

- "Create an infographic"

- "Make a process diagram"

- "Visualize this data"

- "Create a timeline"

- "Show comparison infographic"

- NOT for: Charts/graphs (use charting library), presentations (use visual-content skill)

## Commands

| Command | Purpose |

|---------|---------|

| `/template-infographic` | Create infographic template |

| `/infographic` | Generate infographic (guided) |

| `/infographic-quick` | Generate infographic (fast) |

## Template Asset Types

| Type | Count | Identifier | Data Format |

|------|-------|------------|-------------|

| **Text-only** | 100+ | (default) | `{ "label": "Cloud", "desc": "Infrastructure" }` |

| **Icon-based** | 8 | `icon` in name | `{ "label": "icon:rocket", "desc": "Fast" }` |

| **Illustrated** | 9 | `-illus` suffix | `{ "label": "Step 1", "desc": "Discovery", "illus": "step-1" }` |

**Recommendation:** Start with text-only templates. Illustrated templates require custom image files.

### Illustrated Template Workflow

When using `-illus` templates:

1. Content includes `illus` field referencing image filename

2. Supported formats: SVG (recommended), PNG, JPG

3. Options: provide your own images, find icons, or use placeholders

4. Images stored with infographic output: `infographics/{date}-{name}/illustrations/`

5. See `references/illustrations.md` for detailed workflow

## Text Guidelines (Avoiding Overlap)

| Element | Max | Good | Bad |

|---------|-----|------|-----|

| Labels | 1-2 words | "Cloud" | "Cloud Computing Services" |

| Descriptions | 2-4 words | "Infrastructure design" | "Complete infrastructure design and implementation" |

If overlap occurs: shorten text, use wider canvas (1200px+), or use column/grid templates.

## Quick Reference

| Task | How |

|------|-----|

| Generate infographic | `node generate.js --config config.json --data '{...}' --output output.png` |

| Set background | `--background "spotlight-dots"` |

| SVG output | `--format svg` |

## Background Presets

## Workflow

### 1. Create Template (once)

```

/template-infographic

```

Select: category → design → palette → background → style

### 2. Generate Infographic (repeat)

```

/infographic-quick

```

Select template → paste content → name → get PNG

## Accessibility & Readability (MANDATORY)

**These checks are NON-NEGOTIABLE before generating any infographic.**

### Contrast Validation (WCAG AA)

| Requirement | Value |

|-------------|-------|

| Minimum contrast ratio | **4.5:1** for all text |

| Large text (title) | 3:1 acceptable |

| Standard | WCAG 2.1 AA |

**Key principle:** Palette colors are for SHAPES and FILLS, not text. Text needs explicit high-contrast colors.

### Text Color Rules by Background

| Background Type | Title Fill | Description Fill | Label Fill |

|-----------------|------------|------------------|------------|

| **Dark** (spotlight-dots, tech-matrix) | White or near-white (WCAG >= 4.5:1) | White at ~85% opacity | White or near-white |

| **Light** (solid, subtle-dots) | Near-black (WCAG >= 4.5:1) | Dark gray | Near-black |

**Never use palette colors for text** - they're for decorative shapes only.

### Spacing & Balance Rules

| Element | Requirement |

|---------|-------------|

| **Item spacing** | Minimum 20px between items |

| **Edge margins** | Never touch canvas edges (min 5% padding) |

| **Text truncation** | Labels 1-2 words, descriptions 2-4 words |

| **Visual balance** | Equal spacing between similar elements |

### Pre-Generation Checklist

```

□ All text has 4.5:1 contrast against background

□ Labels are 1-2 words (no overlap risk)

□ Descriptions are 2-4 words

□ Content fits template capacity (check item limits)

□ Dark bg → white text, Light bg → dark text

□ No text touching edges

□ colorBg derived from brand-philosophy.md, not from skill defaults

□ colorPrimary derived from brand-philosophy.md, not from skill defaults

□ Colors traced to brand-philosophy.md (not copied from reference docs or runtime fallbacks)

□ font-family from brand-philosophy.md, not a generic default

□ Text colors WCAG-validated against actual background

```

**If ANY check fails, DO NOT generate. Fix the content or config first.**

## Data Structure by Type

## Common Mistakes

| Mistake | Fix |

|---------|-----|

| Text overlapping | Shorten labels (1-2 words), descriptions (2-4 words) |

| Missing illustrations | Check template ends in `-illus`, provide SVG/PNG/JPG files |

| Icon not showing | Use `icon:name` syntax, only for icon templates |

| Background not applied | Pass `--background` flag to generate.js |

| Text invisible on light bg | Add explicit `title`/`desc`/`item` fills with dark colors (#1A202C, #4A5568) |

| Pastel text unreadable | Palette colors are for shapes only; text needs high contrast (~4.5:1) |
