FAQPage Schema

How do I create a JSON Canvas file for visual diagrams in Obsidian?▼

To create a JSON Canvas file, define two top-level arrays for nodes and edges to model diagrams. You can structure text, file, link, and group nodes, then connect them using edges to build visual planning canvases.

What node types are supported by the JSON Canvas spec?▼

The JSON Canvas spec supports four node types: text, file, link, and group. Each node type can be customized with specific colors, layout attributes, and z-index layering for structured visual organization.

How do I build mind maps and flowcharts using JSON Canvas?▼

You build mind maps and flowcharts by defining structured nodes and connecting them with edges in a .canvas file. This programmatic approach replaces ad-hoc sketches and enables programmatic manipulation of visual diagrams.

Does JSON Canvas support layering and background colors for groups?▼

Yes, JSON Canvas supports layering through z-index management and allows you to apply colors and group backgrounds. This ensures proper visual hierarchy when modeling complex research canvases or project boards.

Can I programmatically generate and edit .canvas files for project boards?▼

You can programmatically generate and edit .canvas files by manipulating the JSON structure containing nodes and edges arrays. This enables automated creation of project dashboards and flowcharts while ensuring compliance with JSON Canvas Spec 1.0.
