JSON Canvas diagrams provide a lightweight, JSON-based way to model visual graphs (nodes and edges) for planning, mapping, and diagramming without heavy tooling. This Skill guides you through creating, editing, and validating .canvas files so you can quickly translate ideas into shareable, machine-readable diagrams.
Create a new .canvas file with the base structure and add two connected nodes.

To create a valid JSON Canvas file, structure your JSON with two top-level arrays named nodes and edges. Each node requires id, type, x, y, width, and height attributes, while edges must use fromNode and toNode references to connect existing nodes.
The JSON Canvas Spec 1.0 schema is a lightweight, JSON-based format for modeling visual graphs. It enforces a strict structure containing nodes and edges arrays, requiring unique node IDs, positional coordinates, and valid edge connectivity references.
Validate JSON Canvas data by checking that all node IDs are unique and that every edge's fromNode and toNode attributes resolve to existing nodes within the nodes array, ensuring strict compliance with the JSON Canvas Spec 1.0.
Yes, you can use JSON Canvas to build flowcharts, mind maps, and project diagrams. Its simple node-edge structure allows you to map visual graphs for planning and rapid visualization within Obsidian or other compatible tools.
Yes, JSON Canvas supports custom geometry and labels for edges. When connecting nodes using fromNode and toNode references, you can optionally specify geometry attributes and labels to provide better clarity for your visual diagrams.
Edge connections fail to resolve when fromNode or toNode references do not match existing node IDs. The JSON Canvas Spec 1.0 requires strict schema validation, meaning all edge references must point to valid, uniquely identified nodes in the nodes array.
