Feature-rich mindmap plugin — multiple layouts, themes, node shapes & line styles, wikilink support, node collapse, PNG export — all from plain markdown headings, no custom syntax needed.

How It Works
Add type: mindmap to any note's frontmatter. The plugin replaces the editor/reading view with a live mind map built from the note's heading hierarchy.
You can also right-click a folder in the file explorer and select Create light mindmap to quickly create a new mindmap file in that folder.

The mind map updates in real time as you edit the source.
Features
Auto-Render from Headings
- Parses all heading levels (
#through######) into a tree - Strips inline markdown (bold, italic, links, wikilinks, code) from node labels
- When multiple top-level headings exist, a virtual root node (named after the file) is created automatically
- Fenced code blocks are skipped during parsing
Layouts
Five layout modes, switchable from the toolbar dropdown or via command:
| Layout | Description |
|---|---|
| Balanced | Children are distributed to both sides of the root, weighted by subtree height |
| Right | All branches expand to the right |
| Left | All branches expand to the left |
| Tree | Top-down tree — root at the top, branches expand downward |
| Radial | Root at the center, branches radiate outward in a circle |
Themes
Seven built-in color palettes:
| Theme | Style |
|---|---|
| Vibrant | Indigo/violet/pink gradient — the default |
| Classic | Earth tones on a warm cream background |
| Fresh | Greens and teals on a light mint background |
| Ocean | Blues and indigos on a pale blue background |
| Sunset | Reds, oranges, and pinks on a warm background |
| Midnight | Neon accents on a dark slate background |
| Slate | Cool blue-grey with a subtle tech grid pattern |
Themes adapt automatically to Obsidian's dark/light mode.
Connection Line Styles
| Style | Shape | Dash |
|---|---|---|
| Smooth | Cubic Bézier curve | Solid |
| Smooth Dashed | Cubic Bézier curve | Dashed |
| Straight | Direct line | Solid |
| Right Angle | Horizontal + vertical segments | Solid |
| Right Angle Dashed | Horizontal + vertical segments | Dashed |
Node Shapes
| Shape | Appearance |
|---|---|
| Rounded | Rounded rectangle (default) |
| Square | Sharp corners |
| Borderless | No border or background on leaf nodes |
| Pill | Fully rounded capsule |
| Doodle | Hand-drawn style with slight rotation |
Pan & Zoom
- Drag the canvas background to pan (mouse or touch)
- Pinch to zoom on touch devices
- Scroll to pan vertically/horizontally
- Ctrl/Cmd + Scroll to zoom in/out around the cursor
- Toolbar buttons: Fit (fit all nodes into view), + / − (step zoom)
Node Editing
Nodes can be edited directly on the canvas — changes are written back to the markdown file:
| Action | Gesture / Key |
|---|---|
| Select node | Click |
| Edit node text | Double-click or F2 |
| Confirm edit | Enter |
| Confirm edit + add child | Tab |
| Cancel edit | Escape |
| Add sibling (without editing) | Select node, press Enter |
| Add child (without editing) | Select node, press Tab |
| Delete node | Select node, press Delete or Backspace |
| Collapse / expand node | Select node, press Space |
| Drag node (change parent) | Drag node to center of another node |
| Drag node (reorder) | Drag node to top/bottom of another node |
| Right-click context menu | Right-click on node |
- The root node cannot be deleted.
- Pressing Enter on the root node has no effect (no sibling can be added above root).
- Pressing Tab on a collapsed node auto-expands it and adds a new child.
- Double-clicking or pressing F2 on a collapsed node auto-expands it and enters edit mode.
- Collapsed nodes display a + badge after the text. The badge is also rendered in exported PNGs.
Right-Click Context Menu
Right-click on any node to open the context menu with quick actions:
| Action | Description |
|---|---|
| Edit | Enter edit mode for the node |
| Add Sibling | Insert a sibling node (not available on root) |
| Add Child | Create a child node (auto-expands if collapsed) |
| Collapse | Toggle collapsed state (only for nodes with children) |
| Delete | Delete the node (not available on root) |
The context menu automatically displays in Chinese or English based on Obsidian's language setting.
Persisted Settings
All per-file display preferences are written to frontmatter and restored on next open:
| Frontmatter key | Values |
|---|---|
mindmap-layout |
balanced / right / left / tree / radial |
mindmap-theme |
vibrant / classic / fresh / ocean / sunset / midnight / slate |
mindmap-line |
curve / straight / polyline / polyline-dashed / curve-dashed |
mindmap-node |
rounded / square / borderless / circle / doodle |
Toggle Source View
- Edit Markdown button in the toolbar hides the mind map and shows a floating Light Mindmap button
- Returning from source view auto-fits the mindmap to the viewport
- Command palette: Toggle mindmap / source view
- Command palette: Cycle mindmap layout (balanced / right / left / tree / radial)
Links & Wiki-links
Markdown links ([text](url)) and wiki-links ([[Note]], [[Note|Alias]]) in heading text are rendered as clickable links on the mindmap canvas.
- External links (
http://...) open in the default browser - Internal links (relative paths like
./note.md) open in a new Obsidian tab - Wiki-links (
[[Note]]) open the target note in a new Obsidian tab — supports shortest paths, relative paths, and aliases natively
During node editing, typing [[ triggers an autocomplete popup that searches all vault notes. Use ↑↓ to navigate, Enter to insert, Escape to dismiss. Links are shown as plain text while editing for easy modification.
Export PNG
Click the Export PNG button in the toolbar to save the current mindmap as a high-resolution PNG image (2x scale). A system file dialog will let you choose the save location.

功能丰富的思维导图插件——多种布局、主题、节点形状与连线样式，支持双向链接、节点折叠、PNG 导出——基于纯 Markdown 标题渲染，无需任何自定义语法。
预览
使用方法
在笔记的 frontmatter 中添加 type: mindmap，插件会自动将编辑/阅读视图替换为实时思维导图，导图内容来自笔记的标题层级。
也可以在文件资源管理器中右键点击文件夹，选择 新建轻量级脑图，快速在该文件夹下创建一个新的脑图文件。
