Infographic Syntax Tool

Purpose

AI Agents follow this skill to generate AntV Infographic DSL syntax to:

1. Convert user content into structured infographic visualizations
2. Select appropriate templates based on content structure
3. Produce valid DSL syntax for native IPE markdown rendering

---

Important Notes

BLOCKING: Read references/prompt.md before generating syntax. It contains the complete DSL specification, template list, and data field rules.

CRITICAL: Output MUST be a plain code block containing only infographic DSL. No JSON, no Markdown, no explanatory text.

CRITICAL: The first line MUST be infographic <template-name> where template-name is from the available templates list in prompt.md.

MANDATORY: Each template category uses a specific data field — do NOT mix fields. See Template-to-Data-Field mapping below.

About

AntV Infographic is a DSL for describing infographic rendering configurations. It uses indentation-based syntax optimized for AI streaming output. IPE natively renders it via infographic code blocks in markdown.

Key Concepts:

• Template — Determines visual layout (e.g., list-row-horizontal-icon-arrow, sequence-timeline-simple)
• Data Block — Contains title, desc, and the primary data field with items
• Theme Block — Optional styling: palette, font, stylize (rough, pattern, gradient)
• Data Fields — Template-specific: lists, sequences, compares, root, items, values, nodes+relations
• Grid System — 2-space indentation; key-value pairs use key space value; arrays use - prefix

Template-to-Data-Field Mapping:

Template Prefix	Data Field	Notes
list-*	lists	Flat items with label/desc/icon
sequence-*	sequences	Ordered steps, optional order asc|desc
compare-*	compares	Supports children for grouped comparison
hierarchy-structure	items	Independent tiers, up to 3 levels deep
hierarchy-* (others)	root	Single root with nested children
relation-*	nodes + relations	Nodes optional for simple graphs
chart-*	values	Numeric data, optional category
Fallback	items	When no specific field matches

Compare Rules:

• compare-binary-* / compare-hierarchy-left-right-*: Exactly 2 root nodes, all items in children
• compare-quadrant-*: Exactly 4 items

Hierarchy Rules:

• hierarchy-* (non-structure): Single root, nest via children — do NOT repeat root

IPE Markdown Embedding:

```infographic
infographic list-row-horizontal-icon-arrow
data
  title My Title
  lists
    - label Item 1
      icon star
```

When to Use

triggers:
  - "create infographic"
  - "infographic diagram"
  - "visualize as infographic"
  - "turn into infographic"
  - "infographic syntax"

not_for:
  - "architecture diagrams → x-ipe-tool-architecture-dsl"

  - "data tables → standard Markdown tables"

Infographic vs Other Tools:

Content Type	Tool
Feature lists, comparisons, processes	Infographic
Software architecture layers	Architecture DSL
Control flow, state machines	Mermaid
Raw data tables	Markdown

Operations

Operation: generate

When: User provides content to convert into an infographic

<operation name="generate">
  <action>
    1. Load DSL specification from references/prompt.md
    2. Analyze content structure: identify items, hierarchy, sequences, comparisons
    3. Select template:
       - IF template_hint provided → validate against available templates list
       - IF no hint → match content structure to template category (see About section mapping)
    4. Map content to data fields:
       - Extract title and description
       - Map items to the correct data field for the selected template
       - Add icon keywords where appropriate
    5. Apply theme if specified:
       - palette colors, font-family, stylize options (rough, pattern, gradient)
    6. Output complete DSL in a plain code block
  </action>
  <constraints>
    - BLOCKING: First line must be `infographic <template-name>` from available list
    - BLOCKING: Use correct data field for template prefix (see mapping table)
    - CRITICAL: 2-space indentation for block nesting
    - CRITICAL: No JSON, Markdown, or explanatory text in output
  </constraints>
  <output>infographic_syntax (plain code block)</output>
</operation>

Operation: refine

When: User wants to update or improve existing infographic DSL

<operation name="refine">
  <action>
    1. Load DSL specification from references/prompt.md
    2. Parse existing_syntax to identify current template, data, and theme
    3. Apply requested changes (content updates, template switch, theme changes)
    4. Validate refined syntax against DSL rules
    5. Output updated DSL in a plain code block
  </action>
  <constraints>
    - BLOCKING: Preserve existing structure unless explicitly asked to change
    - CRITICAL: Re-validate data field matches template after any template change
  </constraints>
  <output>infographic_syntax (plain code block)</output>
</operation>

Output Result

operation_output:
  success: true | false
  result:
    template_used: "{template-name}"
    infographic_syntax: "{complete DSL}"
    data_field_used: "{lists|sequences|compares|root|items|values|nodes}"
  errors: []

Definition of Done

CRITICAL: Use a sub-agent to validate DoD checkpoints independently.

<definition_of_done>
  <checkpoint required="true">
    <name>Entry Line Valid</name>
    <verification>First line matches `infographic &lt;template-name&gt;` where template-name is in available templates list</verification>
  </checkpoint>
  <checkpoint required="true">
    <name>Block Structure Valid</name>
    <verification>Uses `data` and optional `theme` blocks with 2-space indentation</verification>
  </checkpoint>
  <checkpoint required="true">
    <name>Data Field Correct</name>
    <verification>Data field matches template prefix (list→lists, sequence→sequences, compare→compares, hierarchy→root/items, chart→values, relation→nodes+relations)</verification>
  </checkpoint>
  <checkpoint required="true">

    <verification>Only ONE primary data field used (no mixing lists+items, sequences+items, etc.)</verification>
  </checkpoint>
  <checkpoint required="true">
    <name>Compare Rules Met</name>
    <verification>Binary compare has exactly 2 root nodes; quadrant has exactly 4 items</verification>
  </checkpoint>
  <checkpoint required="true">
    <name>Hierarchy Rules Met</name>
    <verification>hierarchy-* (non-structure) uses single `root` with `children` nesting, no repeated root</verification>
  </checkpoint>
  <checkpoint required="true">
    <name>Indentation Correct</name>
    <verification>Consistent 2-space indentation throughout, key-value pairs use `key space value`</verification>
  </checkpoint>
  <checkpoint required="true">
    <name>No Forbidden Output</name>
    <verification>Output contains no JSON, Markdown formatting, or explanatory text — only DSL syntax</verification>
  </checkpoint>

  <validation_sub_agent>
    <instructions>
      After generating infographic syntax, launch a sub-agent (model hint: haiku) to independently validate:
      1. Parse the output and verify first line matches `infographic {template}` where {template} is in the available templates list from references/prompt.md
      2. Verify only one primary data field is used and it matches the template prefix
      3. For compare-binary-*/compare-hierarchy-left-right-*: verify exactly 2 root compares nodes
      4. For hierarchy-* (non-structure): verify single root, no duplicate root
      5. Verify 2-space indentation is consistent
      6. Verify output contains no JSON, no markdown, no explanatory text
      Report: PASS/FAIL per checkpoint with specific violations if any.
    </instructions>
  </validation_sub_agent>
