I don't think github should (generally) render stuff in the browser (although I see that both "benign"[1] graphs and source code highlights, not to mention the somewhat simple translation from Markdown to html - probably could be done in the browser as js/wasm.

But for "markdown the language" having a standard syntax for embed/evaluate along with prettify/highlight would've been nice - effectively a standard markup for multi-language "notebooks"/literate programs (maybe we need a triplet: format, render/embed, transclude/literate programming).

Github could then opt-in to highlighting the N languages they do, and initially only try to render mermaid graphs. Then perhaps also graphviz graphs. Etc.

[1] I'm sure one could do some minor DOS at least with a 500 mb graph..
