Agent Skills: 学习笔记可视化Canvas技能

学习笔记可视化Canvas技能

🎨 设计理念

为学习笔记优化的可视化系统，实现：

• 知识结构化: 将抽象概念转化为直观图形
• 关系可视化: 清晰展示知识间的关联
• 路径规划: 可视化学习进程和路径
• 思维整理: 支持头脑风暴和概念梳理

📊 核心应用

JSON Canvas = 节点系统 + 连接关系 + 布局算法

• 节点类型: 文本、文件、链接、分组
• 连接系统: 有向边、无向边、标签边
• 布局模式: 层次、网状、自由布局
• 交互功能: 缩放、拖拽、折叠展开

File Structure

A canvas file contains two top-level arrays:

{
  "nodes": [],
  "edges": []
}

• nodes (optional): Array of node objects
• edges (optional): Array of edge objects connecting nodes

Nodes

Nodes are objects placed on the canvas. There are four node types:

• text - Text content with Markdown
• file - Reference to files/attachments
• link - External URL
• group - Visual container for other nodes

Z-Index Ordering

Nodes are ordered by z-index in the array:

• First node = bottom layer (displayed below others)
• Last node = top layer (displayed above others)

Generic Node Attributes

All nodes share these attributes:

| Attribute | Required | Type | Description | |-----------|----------|------|-------------| | id | Yes | string | Unique identifier for the node | | type | Yes | string | Node type: text, file, link, or group | | x | Yes | integer | X position in pixels | | y | Yes | integer | Y position in pixels | | width | Yes | integer | Width in pixels | | height | Yes | integer | Height in pixels | | color | No | canvasColor | Node color (see Color section) |

Text Nodes

  "text": "# Hello World\n\nThis is **Markdown** content."
}

{
  "id": "d4e5f6789012345a",
  "type": "group",
  "x": -50,
  "y": -50,
  "width": 1000,

}

| Attribute | Required | Type | Description | |-----------|----------|------|-------------| | label | No | string | Text label for the group | | background | No | string | Path to background image | | backgroundStyle | No | string | Background rendering style |

Background Styles

| Value | Description | |-------|-------------| | cover | Fills entire width and height of node | | ratio | Maintains aspect ratio of background image | | repeat | Repeats image as pattern in both directions |

Edges

Edges are lines connecting nodes.

{
  "id": "f67890123456789a",
  "fromNode": "6f0ad84f44ce9c17",
  "toNode": "a1b2c3d4e5f67890"
}

Colors

The canvasColor type can be specified in two ways:

Hex Colors

{
  "color": "#FF0000"
}

Preset Colors

{
  "color": "1"
}

| Preset | Color | |--------|-------| | "1" | Red | | "2" | Orange | | "3" | Yellow | | "4" | Green | | "5" | Cyan | | "6" | Purple |

ID Generation

Node and edge IDs must be unique strings. Obsidian generates 16-character hexadecimal IDs:

"id": "6f0ad84f44ce9c17"
"id": "a3b2c1d0e9f8g7h6"
"id": "1234567890abcdef"

This format is a 16-character lowercase hex string (64-bit random value).
