oooo nice!

i haven't used digraph before -- is this the right tooling to be able to view the diagram? we've used mermaid elsewhere which at first glance seems to make it a bit easier to see the rendered diagram.

i looked for a VS code extension and found TS prop dag, but i haven't been able to render the diagram using that tool.

The package is graphviz, specifically the dot layout. I'll update the comments to include that reference.

It looks like there are a couple of online graphviz sites like https://dreampuf.github.io/GraphvizOnline/ but they don't support some of the newer directives I'm using, so I fixed those too.

Yeah, I found mermaid which lets you embed directly in github markdown and tried to port this over, but it really doesn't quite have the same flexability as graphviz.
