This is very cool. Reminds me of my days 13 years ago using dot to draw complex planaarized graph diagrams before switching to physics / springs models, graph embeddings, and other cool things.

Nice to see a really good use for dot.

I created a fork on GitHub as a fork there'll be easier for me to come back to, find, organize and use (and may be for others too): https://github.com/o0101/sqlite-schema-diagram

I hope you don't mind? If you don't want ur code there let me know and I'll sadly but obediently take it down and just link to it from someplace on there I can readily find. :)
