Yeah, that’s precisely why I didn’t tackle that. I was wondering though, does it render text in GL on the web, or leverage the DOM? (I’m just using absolute positioning for the tile labels)

They’re drawn in WebGL using signed distance fields.

It renders in WebGL with SDFs, but rendering is a small part of the problem — placing labels along paths including curved ones, avoiding collisions etc. gets very complex very fast.
