antv-infographic

Infographics convert data, information, and knowledge into perceptible visual language. They combine visual design with data visualization, compressing complex information with intuitive symbols to help audiences quickly understand and remember key points.

Infographic = Information Structure + Visual Expression

This task uses AntV Infographic to create visual infographics.

Before starting the task, you need to understand the AntV Infographic syntax specifications, including template list, data structure, themes, etc.

Specifications

AntV Infographic Syntax

AntV Infographic syntax is a custom DSL used to describe infographic rendering configurations. It uses indentation to describe information, has strong robustness, and is convenient for AI streaming output and infographic rendering. It mainly contains the following information:

1. template: Use templates to express the text information structure.
2. data: Infographic data, including title, desc, data items, etc. Data items typically contain fields such as label, desc, icon, etc.
3. theme: Theme contains style configurations such as palette, font, etc.

For example:

infographic list-row-horizontal-icon-arrow
data
  title Title
  desc Description
  lists
    - label Label
      value 12.5
      desc Explanation
      icon document text
theme
  palette #3b82f6 #8b5cf6 #f97316

Syntax Specifications

• The first line must be infographic <template-name>, template selected from the list below (see "Available Templates" section).
• Use data / theme blocks, with two-space indentation within blocks.
• Key-value pairs use "key space value"; arrays use - as entry prefix.
• icon uses icon keywords (e.g., star fill).
• data should contain title/desc + template-specific main data field (not necessarily items).
• Main data field selection (use only one, avoid mixing):
  • list-* → lists
  • sequence-* → sequences (optional order asc|desc)
  • compare-* → compares (supports children for grouped comparisons), can contain multiple comparison items
  • hierarchy-structure → items (each item corresponds to an independent hierarchy, each level can contain sub-items, can be nested up to 3 levels)
  • hierarchy-* → single root (tree structure, nested through children);
  • relation-* → nodes + relations; simple relation diagrams can omit nodes, using arrow syntax in relations
  • chart-* → values (numeric statistics, optional category)
  • Use items as fallback when uncertain
• compare-binary-* / compare-hierarchy-left-right-* binary templates: must have two root nodes, all comparison items hang under these two root nodes' children
• hierarchy-*: use single root, nested through children (do not repeat root)
• theme is used to customize themes (palette, font, etc.) For example: dark theme + custom color scheme

  infographic list-row-horizontal-icon-arrow
  theme dark
    palette
      - #61DDAA
      - #F6BD16
      - #F08BB4

• Use theme.base.text.font-family to specify font, such as handwriting style 851tegakizatsu

• Use theme.stylize to select built-in styles and pass parameters Common styles:

  • rough: hand-drawn effect
  • pattern: pattern fill
  • linear-gradient / radial-gradient: linear/radial gradient

  For example: hand-drawn style (rough)

  infographic list-row-horizontal-icon-arrow
  theme
    stylize rough
    base
      text
        font-family 851tegakizatsu

• Do not output JSON, Markdown, or explanatory text

Generation Process

Step 1: Understand User Requirements

Before creating an infographic, first understand the user's needs and the information they want to express, in order to determine the template and data structure.

If the user provides a clear content description, it should be broken down into a clear and concise structure.

Otherwise, clarification from the user is needed (e.g., "Please provide a clear and concise content description.", "Which template do you want to use?")

• Extract key information structure (title, desc, items, etc.).
• Clarify required data fields (title, desc, items, label, value, icon, etc.).
• Select appropriate template.
• Describe infographic content using AntV Infographic syntax {syntax}.

Key Note: Must respect the language of user input. For example, if the user inputs in Chinese, the text in the syntax must also be in Chinese.

Step 2: Render the Infographic

When you have the final AntV Infographic syntax, you can generate a complete HTML file following these steps:

1. Create a complete HTML file with the following structure:
   • DOCTYPE and HTML meta (charset: utf-8)
   • Title: {title} - Infographic
   • Include AntV Infographic script: https://unpkg.com/@antv/infographic@latest/dist/infographic.min.js
   • Create container div with id container
   • Initialize Infographic (width: '100%', height: '100%')
   • Replace {title} with actual title
   • Replace {syntax} with actual AntV Infographic syntax
   • Add SVG export functionality: const svgDataUrl = await infographic.toDataURL({ type: 'svg' });

Reference HTML template:

<div id="container"></div>
<script src="https://unpkg.com/@antv/infographic@latest/dist/infographic.min.js"></script>
<script>
 const infographic = new AntVInfographic.Infographic({
    container: '#container',
    width: '100%',
    height: '100%',
  });
  document.fonts?.ready.then(() => {
    infographic.render(`{syntax}`);
  }).catch((error) => {
    console.error('Error waiting for fonts to load:', error);
    infographic.render(`{syntax}`);
  });
</script>

2. Use the Write tool to generate HTML file, named as <title>-infographic.html
3. Show to user:
   • Generate file path and prompt: "Open directly with a browser to view and save as SVG"
   • Output syntax and prompt: "Tell me if you need to adjust template/colors/content"

Note: The HTML file must include:

• SVG export via export button
• Container is responsive, both width and height are 100%
