mindmap

Create hierarchical mind maps using PlantUML @startmindmap syntax. Best for brainstorming, topic decomposition, study notes, and decision trees with automatic radial layout, left/right branches, and per-node styling.

Install the mindmap skill, then use it as build context. Run: npx skills add https://github.com/markdown-viewer/skills --skill mindmap. Then read the installed skill.md and follow its guidance to build or refactor my project.

Mind Map Diagram Generator

Quick Start: Start with @startmindmap -> define root and branches with * or +/- markers -> optionally set branch side, direction, and styles -> wrap in ```plantuml fence.

⚠️ IMPORTANT: Always use ```plantuml or ```puml code fence. NEVER use ```text — it will NOT render as a diagram.

Critical Rules

  • Every diagram starts with @startmindmap and ends with @endmindmap
  • Each hierarchy level is represented by repeating markers:
    • * style: * (root), ** (level 1), *** (level 2)
    • +/- style: + grows left branch, - grows right branch
  • Keep one marker style consistent in the same local branch (do not randomly mix indentation styles)
  • Use left side to switch subsequent branches to the left side of the root
  • Use direction keywords when needed:
    • top to bottom direction
    • right to left direction
  • Multi-line node content must use block syntax:
    • **:Line 1\nLine 2;
  • For quick color coding, use inline node color:
    • *[#Orange] Root
    • **[#lightgreen] Child
  • For reusable themes, define <style> and apply stereotypes like <<green>>
  • Rich text/Creole and icon syntax are supported inside node text (see examples)

Node Syntax Cheat Sheet

** ChildFirst-level child** Goals

Branch Side and Direction

ControlSyntaxUse Case
Left-side splitleft sideSplit map into left/right groups from root
Top-to-bottomtop to bottom directionTree-like vertical hierarchy
Right-to-leftright to left directionRTL reading flow or mirrored layouts

Styling Options

MethodSyntaxBest For
Inline node color**[#FFBBCC] IdeaFast per-node emphasis
Reusable class style<style> ... .green { ... } </style> + <<green>>Consistent visual themes
Depth-based style:depth(1) { ... }Global formatting by hierarchy depth
Node/arrow global stylenode { ... } / arrow { ... }Unified typography and connectors

Recommended Color Palettes

Pick a palette that matches the map's purpose. Use inline [#hex] for quick coloring or define <style> classes for reuse.

Tip: Avoid pure saturated colors (#FF0000, #00FF00) — they reduce readability. Prefer soft/muted tones for backgrounds and reserve bold colors for the root only.

Common Pitfalls

IssueSolution
Diagram not renderedUse ```plantuml fence + @startmindmap ... @endmindmap
Branch depth looks wrongCheck marker count (*, **, ***) and indentation consistency
Multi-line text breaks parserUse : ... ; block syntax, ensure trailing ; exists
Colors not appliedVerify hex format (#RRGGBB) or stereotype class names
Layout direction unexpectedAdd explicit top to bottom direction or right to left direction
