Love it! I created a VSCode extension to render it in markdown files and highlight its syntax: https://github.com/volkanunsal/relative-diagrams-vscode/

Thanks for making that! Just a heads up, reladraw is changing super fast - I think the rendering/highlighting will work smoothly with syntax changes, the more annoying thing would be any JS API breaking changes.

No problem! I hooked up dependabot to detect upstream changes, so when you bump up the version number, it should create a PR and bump the version number of the extension, and I will merge. I think the unit tests should catch any regression.
