Generates hierarchical mind maps using PlantUML's mindmap syntax, wrapped in plantuml code fences so they render as diagrams. You get radial layouts with star or plus/minus markers to define depth and branch sides, inline color coding with hex values, and optional style blocks for theming. Works well for brainstorming sessions, pros/cons splits, project breakdowns, or study outlines where you need visual hierarchy. The source includes six color palettes ranging from pastel to earth tone, plus pattern examples for bilateral layouts and boxless branches. One catch: multi-line nodes need the colon-semicolon block syntax or the parser chokes. If you're already using PlantUML for other diagrams, this slots right in.
