This is great. It doesn’t seem to work with mindmaps and timelines though. I tried forking it and updating to Mermaid v9.4.0, but I’m still getting an error. This code works in their live editor, but not in Discourse, even with Mermaid v9.4.0:

mindmap
Root
    A
      B
      C

also this one, but it doesn’t work in their live editor either, which appears to be running v9.3.0. It does run in a plain HTML page using v9.4.0.

If I figure it out I’ll post back here.
