This is a README file for an Obsidian plugin called "Advanced Canvas". The plugin adds various features to the canvas in Obsidian, such as:

• Custom styles: Users can add custom CSS styles to nodes and edges on the canvas.
• Custom colors: Users can add custom colors to nodes and edges on the canvas.
• Node interactions: Users can interact with nodes on the canvas, such as moving them around or resizing them.
• Edge interactions: Users can interact with edges on the canvas, such as dragging them to reposition them.
• Zooming and panning: Users can zoom in and out of the canvas using keyboard shortcuts or mouse gestures.
• Undo and redo: Users can undo and redo changes they make to the canvas.
• Read-only mode: Users can set the canvas to read-only mode, which prevents them from making changes to it.

The plugin also provides a range of events that plugins can use to interact with the canvas. These events include:

• advanced-canvas:node-interaction: Fired when a node is interacted with (e.g. moved or resized).
• advanced-canvas:edge-interaction: Fired when an edge is interacted with (e.g. dragged to reposition it).
• advanced-canvas:undo: Fired when the user undoes a change they made to the canvas.
• advanced-canvas:redo: Fired when the user redoes a change they made to the canvas.
• advanced-canvas:readonly-changed: Fired when the read-only state of the canvas changes.
• advanced-canvas:data-requested: Fired when the canvas data is requested (e.g. by another plugin).
• advanced-canvas:load-data: Fired when the canvas data is set.
• advanced-canvas:canvas-saved:before and advanced-canvas:canvas-saved:after: Fired before and after the canvas is saved.

The README file also includes a section on contributing to the plugin, which provides information on how to submit pull requests and issues. Additionally, there is a star history chart at the bottom of the file that shows the number of stars the plugin has received over time.
