# Mindmaps

> Plain-text .mindmap.md files with an interactive canvas view.

* **Plain-text format** a `.mindmap.md` file is a lightweight, strict subset of Mermaid's `mindmap` syntax: `mindmap` on the first line, a `root((Label))` on the second, then an indented tree, one node per line, indentation depth defines parent/child structure
* **Two views, one file** open as plain text in a Code tab like any markdown file, or Cmd+Shift+X for an interactive Canvas tab that live-updates as the source text changes
* **Node shapes** wrap a label in `(Label)` for rounded, `[Label]` for square, `((Label))` for circle, or leave it bare for a default box; purely visual, doesn't affect tree structure
* **Node colors** trailing `{fill}` and `{fill} {border}` markers accept hex or any CSS color name; the root's markers set the whole mindmap's default fill/border, which every other node inherits unless it sets its own; text color auto-picks black/white for legibility against the fill
* **Math in labels** a label containing `$...$`/`$$...$$` renders as typeset LaTeX math via KaTeX (see [Math Formulas](/math)) instead of literal text; node sizing accounts for the rendered formula so math-heavy nodes don't clip
* **Interactive canvas** pan by dragging the background, zoom with Cmd/Ctrl+scroll (zooms toward the cursor); drag any node to reposition it, with snap-to-grid toggleable in the toolbar
* **Multi-select** marquee-select (toolbar toggle or hold Shift) to select several nodes and drag them together, preserving their relative layout
* **Persistent layout** dragged positions save to a `.mindmap.md.layout.json` sidecar next to the source file, so manual rearrangement survives reopening the canvas
* **Export** toolbar buttons export the current canvas view as PNG or PDF
* **Parse errors are line-numbered** malformed syntax shows exactly which line and why, right in the canvas view, instead of failing silently
