I thought your playground wasn't working as it renders black text on black background. Maybe I have darkmode enabled or something. Other renderers work, but ascii is invisible.

Ah right, forgot to test the update with dark mode. Thanks for letting me know!

edit: fixed

Does the SVG renderer support custom IDs and/or attributes on nodes? If so I'll add support for this to Stylus (https://github.com/mmastrac/stylus)

Yeah I think what you're looking for is the note at the end of this section: https://d2lang.com/tour/exports/#svg

Feel free to make a PR to d2/d2-docs to include it in our list of community tools/plugins if you do!
