Create Valid JSON Canvas Diagrams

Creating Obsidian canvas files by hand can cause invalid nodes, edges, and layout data. This skill guides Claude, Codex, and Claude Code to produce valid JSON Canvas structures.

Install with my Agent

Copy this request to your Agent. It includes the canonical Skill page and manifest.

Agent request
Review the Skillstore skill "json-canvas" from https://skillstore.io/skills/zhanlincui-json-canvas.md and its manifest at https://skillstore.io/api/skills/zhanlincui-json-canvas/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.

Your Agent should still show its plan and request any confirmation required by the security policy.

Test it

Using "json-canvas". A user asks for a mind map about a product launch plan.

Expected outcome:

  • A central launch plan node with supporting strategy, timeline, risks, and metrics nodes.
  • Edges connect each support node to the central topic with clear labels.
  • The layout uses consistent spacing and valid canvas node dimensions.

Using "json-canvas". A user wants a research canvas for notes, papers, and links.

Expected outcome:

  • A research question node anchors the canvas.
  • File and link nodes represent source material without creating those files.
  • Labeled edges show which sources support, challenge, or illustrate the topic.

Using "json-canvas". A user provides a broken canvas with missing edge targets.

Expected outcome:

  • A validation review identifies missing node references and unsupported field values.
  • The corrected canvas keeps the original intent while using valid node and edge rules.

What You Can Build

Map Research Sources

Create a canvas that connects papers, notes, links, and central research questions.

Plan Project Boards

Build grouped boards with task cards, status lanes, and clear visual spacing.

Draft Knowledge Maps

Turn outlines into connected visual notes for Obsidian or another JSON Canvas viewer.

Try These Prompts

Simple Mind Map 
Create a simple JSON Canvas mind map for this topic. Use one central text node, three supporting text nodes, and labeled edges.
Organized Project Board 
Create an Obsidian .canvas project board with To Do, In Progress, and Done groups. Add task nodes with readable spacing.
Research Canvas With Sources 
Create a research canvas from these notes. Include text nodes, file nodes, link nodes, and edges that explain each relationship.
Validate And Improve Canvas 
Review this .canvas structure for missing fields, invalid references, poor spacing, and unclear labels. Return a corrected version and explain changes.

Best Practices

  • Use unique 16-character IDs for every node and edge.
  • Keep node spacing consistent so the canvas stays readable.
  • Check every edge endpoint against an existing node ID.

Avoid

  • Do not reuse node IDs across different items.
  • Do not point file nodes to attachments that do not exist.
  • Do not crowd many nodes into the same coordinates.

Frequently Asked Questions

What is JSON Canvas?
JSON Canvas is an open format for infinite canvas data used by Obsidian and related tools.
Can this skill create Obsidian .canvas files?
Yes. It guides the agent to create valid .canvas structures with nodes, edges, groups, and layout data.
Does this skill render the canvas visually?
No. It creates or reviews the canvas data, but a compatible app must render the visual view.
Can it include files and links?
Yes. It documents file nodes and link nodes, including paths, subpaths, and external URLs.
Can it repair an existing canvas?
Yes. It can review required fields, node references, allowed values, and layout clarity.
Does it run commands or access the network?
No. The skill is documentation only. It contains examples and reference links, not executable tooling.
