How does it handle node positioning and overlapping?

The skill includes layout guidelines that suggest specific widths and heights for different node types and maintains 50-100px spacing to prevent visual clutter.

What is the JSON Canvas format?

JSON Canvas is an open-source file format (.canvas) designed for infinite visual canvases, allowing users to connect nodes, text, and files in a structured JSON schema.

Does it support Markdown within the canvas?

Yes, text nodes created by this skill fully support Markdown syntax, including headers, bold text, and lists, which render correctly in compatible viewers.

Can Claude generate flowcharts from my source code using this?

Absolutely. Claude can use this skill to parse your logic and output a visual .canvas file representing your code architecture or execution flow.

Is this skill compatible with Obsidian?

Yes, it follows the JSON Canvas Spec 1.0, which is the native format used by Obsidian for its Canvas plugin, ensuring full interoperability for your notes.
