It looks like the CLI tool (@penrose/roger) just depends on a few npm packages with no browser engine and supports SVG export.

Looks like that depends on the “canvas” package, which appears to use Cairo/Pango for text, similar to Graphviz.

This is great! I wanted something I could compile (the native code) to WebAssembly for use in a Deno-based SSG, and this looks promising.

I think they were working on an Obsidian plug-in at some point, and got some primitive functionality up, but don’t know what the state of that is currently.

So possible rendering point, though I guess falls under browser engine
