GitHub Markdown now Supports Mermaid Diagrams

edit ✏️

Mermaid diagrams provide a way to display graphs defined as plain text. Some markdown renderers support this as a plugin. GitHub now supports it.

example

You can define nodes like this in mermaid, and GitHub will now render them as a pretty graph diagram. Its rendered in svg, so its searchable with control f and everything.

  graph TD;
      A-->B;
      A-->C;
      B-->D;
      C-->D-->OUT;
      E-->F-->G-->OUT
