Does anyone have a similar solution for drawing graphs / charts in a Node environment without a browser dependency? Last time I explored this I couldn't find any good solutions.

You could use https://github.com/vercel/satori which supports Node 16+.

Unfortunately not for nested inline nodes, like spans of text with formatting. For a lot of uses, that will be OK - but for rendering say, markdown text, Satori won't work.

The upstream layout engine handles flexbox layout, and it's unclear if Facebook needs inline layout or if Vercel would pick it up and close the gap: https://github.com/facebook/yoga

Then again, for the main purpose Satori is advertised for - generating URL unfurl previews - Dropflow looks like it might be the answer.

Thanks. I've tried using Satori but I'm curious if you've used it to draw graphs specifically. E.g. Satori expects JSX / doesn't support HTML strings from d3-node with dangerouslySetInnerHTML.

Does this depend on a browser? It looks like it doesn't - which is pretty impressive!

Do you need to create images?

It's trivial to create svg in the server. It's like rendering html.
