Terminology
Canvas: The canvas view is the view in which nodes and edges are displayed.
Node: A node is a single element in a canvas that can contain text, files, or links. (Some people also call it card or element - but please always use node.)
Text Node: A text node is a node that contains text.
File Node: A file node is a node that contains a link to another file.
Group Node: A group node is a node that contains other nodes.
Link Node: A link node is a node that displays a website.
Edge: An edge is a connection between two nodes in a canvas. It can be used to represent relationships or connections between different elements. (Please always use edge instead of arrow to avoid confusion with the edge arrow.)
Edge Path: The edge path is just the line that connects two nodes in a canvas.
Edge Arrow: The edge arrow is the arrow at the end (or start) of an edge that indicates the direction of the connection.
Popup Menu: The popup menu is the horizontal menu that is visible if one or more canvas elements (nodes or edges) are selected.
Context Menu: The context menu is menu that is visible if you right-click in a canvas view.
Control Menu: The control menu is the vertical menu that is visible in the top right corner of a canvas view.
Card Menu: The card menu is the horizontal menu at the bottom of the canvas view where you can find options to create new nodes.
Standardized Format
Compatible with the JSON Canvas format, the Advanced JSON Canvas format takes it a step further by adding more features and flexibility. The Advanced JSON Canvas format was introduced to provide longevity, readability, interoperability, and extensibility for canvases created with Advanced Canvas.
Full Metadata Cache Support
Advanced Canvas enables .canvas files to be indexed by the metadata cache. This means that there is now full compatibility with the graph view, outgoing links and backlinks. You can even enable (optional) the creation of an outgoing link if two embeds in a canvas are connected by an edge. This feature brings the full power of Obsidian's linking system to the canvas file format.
Metadata Cache Support ExampleOutgoing Link Using An Edge ExampleTechnical Details
The file cache of a .canvas file now contains a value for the hash key (Generated from the filepath) instead of an empty string.
Check the app.metadataCache.fileCache[<filepath>] object to see the changes.
The metadata cache is located in the app.metadataCache object - the same object that is used by Obsidian for markdown files.
e.g. app.metadataCache.getCache/app.metadataCache.getFileCache now works with .canvas files.
The position object which is found inside metadata cache entries now contains a new key nodeId for .canvas files.
The metadata cache entry for a .canvas file now contains a new key nodes which is an object of type { [nodeId: string]: MetadataCacheEntry } - this allows for other plugins to access the full metadata cache for single nodes. The MetadataCacheEntry object is the same as for markdown files (even created with the same function - 1:1 compatibility).
The resolved links object now has entries for .canvas files.
The app.metadataCache.resolvedLinks object values for .canvas files are implemented in the exact same way as for markdown files.
Frontmatter Support
Additionally, Advanced Canvas introduces full frontmatter support for .canvas files. You can now view and edit the frontmatter directly within the canvas view:
Accessing Frontmatter: Click the "info" icon located in the top right corner of the canvas view.
Functionality: This allows you to add custom properties (metadata) to your canvas files.
Use Cases:
Categorization & Tagging: Add tags or custom keys for organization.
Aliases: Use aliases to create alternative names for your canvas files.
Styling: Use cssclasses to apply custom CSS styles to the entire canvas view.
Custom Metadata: Define any other properties relevant to your workflow.
Searchability: Properties defined in the frontmatter of your .canvas files are searchable using Obsidian's global search pane, further integrating canvases into your knowledge management system.
This significantly enhances the ability to manage, organize, and customize your canvases alongside your other notes in Obsidian.
Auto File Node Edges
Advanced Canvas can automatically create edges between file nodes based on their frontmatter properties. By default (if enabled), it will create edges to files linked in the canvas-edges frontmatter property. This allows you to create fixed relationships between file nodes in your canvas, making it easier to visualize fixed structures or connections between different files.
Single Node Links & Embeds
Advanced Canvas now allows you to link or embed the content of a single node from a .canvas file directly into your markdown files. This provides a granular way to reference specific pieces of information within your canvases.
Syntax:
Linking: Use the standard wikilink format with the node ID appended after a #:
[[canvas-file-name#node-id]]
Embedding: Use the standard embed wikilink format, also with the node ID:
![[canvas-file-name#node-id]]
Functionality: When you link or embed a node this way, the actual content of that specific node from the canvas will be displayed or linked within your markdown file. This is incredibly useful for creating direct references to diagrams, text snippets, or any other content held within individual canvas nodes.
Better Default Settings
Enforce all new nodes to be aligned to the grid
Customize default text node size
Customize default file node size
Modify the minimum node size
Disable the font scaling relative to the zoom level
Native-Like File Search
Quickly locate text within your canvas using a familiar search experience. Advanced Canvas integrates a native-like file search specifically for canvas content.
Activation: Use the Search current file command, which is commonly bound to the Ctrl+F (or Cmd+F on macOS) keyboard shortcut.
Functionality: This opens a search interface that allows you to search for text across all nodes within the currently active canvas.
Benefits: Easily find specific information, navigate to relevant nodes, and streamline your workflow when dealing with text-heavy canvases.

Border Styles Example
(Note: Text Alignment options (Left, Center, Right) are also available for nodes.)
Edge Styles
You can customize the default edge styles using the settings.
Path Styles
Set the style of the edge paths to dotted, short-dashed or long-dashed.
Edge Path Styles Example
Arrow Styles
Set the style of the arrows to triangle outline, halved triangle, thin triangle, diamond, diamond outline, circle, circle outline and blunted.
Arrow Styles Example
Pathfinding Methods
Set the pathfinding method of the edges (arrows) to default, straight, squared or A*.
Edge Pathfinding Methods Example
Custom Styles
Custom style attributes for nodes and edges can easily be added. They get exposed in the .canvas-node dataset (for nodes) or .canvas-edges path dataset (for edges) and can be styled using CSS. Node styles also get exposed in the node editor iframe in the body dataset and the class canvas-node-iframe-body indicating that the body is inside a canvas node iframe.
Create a new CSS snippet in your vault:
Navigate to Settings > Appearance > *scroll down* > CSS snippets and click on the folder icon to open the snippets folder.
Create a new CSS file (e.g. my-fancy-node-style.css).
Add the custom style attribute definition:
Open the CSS file and add the following code. The format needs to be YAML (within a CSS comment) and must contain the same keys as in this example. The number of options can be adjusted (minimum of one option is required). The icon key should contain the ID of an icon from lucide.dev.
Change @advanced-canvas-node-style to @advanced-canvas-edge-style for edge styles.
Enable the CSS snippet in Obsidian's settings and enjoy your new custom style attribute!Example in Popup Menu
See an example of a complete custom node style CSS file here.
Variable Breakpoints
Add breakpoints to nodes to change at which zoom factor the node's content gets unrendered.
[!IMPORTANT]
Due to performance reasons, custom breakpoints get cached and are only re-fetched when the canvas gets reloaded. Changes in the CSS snippet won't be applied immediately (only after reopening the canvas).
Create a new CSS snippet in your vault (and enable it in settings):
/* Any CSS selector can be used (As long as the .canvas-node element has the CSS variable defined) */
.canvas-node[data-shape="pill"] {
/* The zoom factor at which the node's content gets unrendered (Zoom level can range from 1 to -4) */
--variable-breakpoint: 0.5;
}
Z-Ordering Control
Change z-ordering of nodes using the context menu.
Z-Ordering Control Example
Custom Colors
Add custom colors to the color picker. You can add them using the following CSS snippet:
body {
/* Where X is the index of the color in the palette (1-6 are used by Obsidian) */
--canvas-color-X: 0, 255, 0; /* RGB values */
}
Custom Colors In Palette Example
Presentation Mode
In presentation mode, you can navigate through nodes using arrow keys or PageUp/PageDown keys (compatible with most presentation remotes). Slides/nodes are connected by arrows. For multiple outgoing arrows from one node, number them to define navigation order. While in presentation mode, the canvas is in readonly mode (so Better Readonly features apply). Exit with ESC or the corresponding command. Use Advanced Canvas: Continue presentation to resume from the last slide.
Simple Presentation Canvas File
More Complex Example

Usage
Create the first slide:
Use the updated popup menu to mark a node as the first slide.
OR create a node and mark it via the updated card menu.
Add more slides:
Link slides using arrows.
To loop back, number arrows for navigation order.
TIP: Use the updated card menu for consistent slide dimensions.
Embed other canvases inside your current canvas and create edges (arrows) to the embedded canvas.
Usage
Embed a canvas file, then click the door icon in the popup menu to open it as a portal.
Collapsible Groups
Collapse and expand groups to organize your canvas.
Collapsible Groups Example
Image Export
Export the whole canvas or just a selection as a PNG/SVG image with transparency. Core plugin export options like "Privacy Mode" and "Show Logo" (extended to include Advanced Canvas logo) are also available.
Image Export Example (SVG)
Auto Node Resizing
Resize nodes automatically when their text content changes. Toggle this feature per-node using the updated popup menu.
Auto Node Resizing Example
Edge Highlight
Highlight edges when a connected node is selected. This feature helps to visually identify relationships between nodes.
If you want to edit the look of the highlighted edges, you need to edit the is-focused CSS class in a custom CSS snippet.
Focus Mode
Focus on a single node by blurring all other nodes.
If "Edge Highlight" is enabled, edges connected to the focused node won't be blurred.
Focus Mode Example
Better Readonly
Disable node popup menus.
Lock the canvas' position.
Lock the canvas' zoom.
Interactivity is retained for zooming to a bounding box (e.g., zoom to selection, zoom to fit all).
Usage
Use the updated control menu to toggle these features (shown only if the canvas is in readonly mode).
Encapsulate Selection
Move the current selection to a new canvas and create a link to it in the current canvas.
Usage
Select the nodes you want to encapsulate.
Use the context menu (right-click) to encapsulate the selection.
OR use the command palette (Advanced Canvas: Encapsulate selection).
Floating Edges (Automatic Edge Side)
Edges automatically change their connection side to the most suitable one.
Drag the edge to the indicated drop zone inside the node to make the edge float.
Floating Edges Example
Flip Edge
Flip the direction of an edge with one click.
Flip Edge Example
Edge Selection
Select edges connected to the selected node(s).
