It was worth trying, since the syntax is easier than graphviz (i.e. there are no references to "postscript overloads" as in graphviz docs).
But [graphviz] seem to generate a huge amount of whitespace. I thought it was just the preview window, but renders in posted post too:
And how to control fontsize= rendering when dot/graphviz goes to SVG here, IDK exactly how...
... and my "Testing:" link above with a lot of Graphviz will somewhat frequently completely hang Safari on macOS, which I use. Chrome seem to work better... Perhaps Safari issue. IDK if same issue with Mermaid
Also empty
[graphviz]tags causes some JS to render in preview. I think it's if you have multiple ones, but see in a few times in testing the graphviz in thread above.
