Content Infographic

Content Infographic Skill

Purpose

Generate production-ready SVG and HTML infographics that are brand-aligned, accessible, and optimized for web, print, and social media embedding. This skill produces visual assets, not presentations or documents.

When This Skill Activates

• User asks for an infographic, data visualization, process diagram, comparison chart, or stat card.
• User has data they want to visualize.
• User needs a visual summary for a blog post, social media, report, or presentation.
• User says "visualize this" or "make this visual" about any data or process.

SVG-First Approach

Always default to SVG output unless the user requests otherwise. SVG advantages:

• Scalable: Looks sharp at any size, from social media thumbnail to conference poster.
• Embeddable: Inline in HTML, embed in markdown, include in presentations.
• Print-ready: No pixelation at any DPI.
• Editable: Users can modify colors, text, and layout after generation.
• Accessible: Supports <title>, <desc>, and aria-label attributes for screen readers.
• Small file size: Vector graphics compress well.

When to use HTML instead of SVG:

• Interactive infographics with hover states, tooltips, or animations.
• Infographics that need responsive reflow at different screen sizes.
• Dashboards with live data bindings.

Generation Flow

Step 1: Read Brand Context

Read these files if they exist:

• brand/VISUAL.md -- colors, fonts, logo rules
• brand/BRAND.md -- identity, audience (affects visual tone)

Extract:

• Primary, secondary, and accent colors
• Font family (or use a clean sans-serif default)
• Logo mark SVG path (for embedding in the infographic)
• Visual style preferences (minimal, bold, playful, corporate)

If brand/ is missing, ask for 2-3 colors and proceed with a clean default style.

Step 2: Understand the Data

Before designing anything, understand what needs to be communicated:

• What is the data? Numbers, categories, processes, comparisons, timelines.
• What is the key insight? Every infographic has one main takeaway. Identify it.
• Who is the audience? Technical vs. general, internal vs. external.
• Where will it live? Blog post, social media, email, print, presentation slide.

Ask clarifying questions if the user provides raw data without context.

Step 3: Choose Layout

Based on the data type and key insight, select the appropriate template type:

See templates/ for each template type.

Step 4: Generate SVG

Build the SVG following these principles:

• Set a viewBox appropriate for the output context (1200x800 for blog embeds, 1080x1080 for social, custom for others).
• Use CSS custom properties for colors so the user can retheme easily.
• Embed brand fonts via <style> inside the SVG or use web-safe fallbacks.
• Include the brand logo mark in a corner (default: bottom-right, small, 50% opacity).
• Add accessibility: <title> for the infographic name, <desc> for a plain-text summary.

Step 5: Validate

Before delivering, check:

• Key insight is immediately visible (the most important information is the largest/most prominent element).
• Color contrast passes WCAG AA for all text.
• No more than 5-6 colors total.
• Text is readable at the intended display size.
• Brand colors and fonts are applied correctly.
• Logo is present but not distracting.
• SVG is valid and renders in all major browsers.

Design Principles

See design-principles.md for the full reference. Key rules:

Data-Ink Ratio

Every visual element should encode data. Remove anything that does not:

• No decorative borders or shadows.
• No 3D effects on charts.
• No background textures or patterns unless they encode information.
• Gridlines should be light gray and minimal (or removed entirely if the axis labels are sufficient).

Color with Meaning

• Use color to encode information, not for decoration.
• Primary brand color for the key data series or most important element.
• Secondary colors for supporting data.
• Neutral gray for context, labels, and axes.
• Never use color as the only differentiator -- pair with labels, patterns, or position for accessibility.

Typography Hierarchy

Three levels maximum:

1. Title: Large, bold. States the key insight, not the chart type. "Revenue grew 47% in Q3" not "Revenue Chart."
2. Labels: Medium, regular weight. Axis labels, category names, data point annotations.
3. Footnotes: Small, light. Sources, methodology notes, date ranges.

Whitespace

Whitespace is not empty space -- it is structure. Use it to:

• Separate sections of the infographic.
• Create visual breathing room around the key insight.
• Guide the eye from one element to the next.

Grid Alignment

Align elements to an invisible grid. Misaligned elements create visual noise. In SVG, use consistent x/y coordinates and spacing values.

Template Types

Data Visualization (templates/data-viz.svg.template)

For quantitative data: bar charts, line charts, donut charts, area charts.

Key rules:

• Start bar chart y-axes at zero (truncated axes mislead).
• Use horizontal bar charts when category labels are long.
• Limit pie/donut charts to 5 segments. Use "Other" for the rest.
• Annotate data points directly on the chart when possible (reduces need for legends).

Process Flow (templates/process-flow.svg.template)

For sequential information: workflows, how-it-works diagrams, timelines, pipelines.

Key rules:

• Flow left-to-right or top-to-bottom. Never right-to-left.
• Each step: icon or number + title + one-line description.
• Connect steps with arrows or lines.
• Use consistent spacing between steps.
• Highlight the current or most important step with the brand accent color.

Comparison (templates/comparison.svg.template)

For side-by-side evaluation: versus layouts, feature matrices, pros/cons, before/after.

Key rules:

• Equal visual weight to both sides (unless the infographic is designed to favor one).
• Clear visual separator (vertical line, color difference, or whitespace).
• Consistent structure: same categories in the same order on both sides.
• Use icons or color coding to indicate positive/negative/neutral.

Stat Card (templates/stat-card.svg.template)

For single key metrics: hero numbers, KPI highlights, social media sharing.

Key rules:

• The number is the largest element by far.
• Context below the number in smaller text.
• Optional: trend indicator (arrow up/down), comparison ("up from 32% last quarter").
• Keep the card focused: one stat, one context line, one optional trend indicator.

Brand Logo Embedding

If brand/logo/logo-mark.svg exists, embed it in the infographic:

<g transform="translate(1120, 750)" opacity="0.5">
  <!-- Contents of logo-mark.svg pasted here -->
</g>

Placement: bottom-right corner by default. Adjust position based on layout. Size: approximately 5-8% of the infographic width. Opacity: 40-60% so it does not compete with the data.

Output Formats

For social media, suggest the user render the SVG to PNG at 2x resolution using a tool like svgexport or a browser screenshot.

Error Handling

• If the user provides no data, ask for it. Do not generate placeholder infographics with fake numbers.
• If the data has too many categories for the chosen format (e.g., 15 items in a pie chart), recommend a different format or suggest grouping.
• If brand/ is missing, proceed with a clean minimal style and note that running content-setup would improve consistency.
• If the data tells no clear story, push back: "What is the one thing you want the viewer to take away from this?"
