@fgregg If you ever need a Python tool to generate your dots, I made this a couple years ago https://github.com/eyeseast/dorchester

@chrisamico beautiful!

i actually implemented something convergent myself.

https://github.com/fgregg/chicago-dots/blob/main/src/points.py

it's heavily numpy-ified so it might be worth bringing some of those ideas over to your library?

@fgregg Very open to PRs, especially anything that makes it faster. I don’t use numpy much, so I’m sure I’m not getting the most out of it.

I also need to upgrade to the latest Shapely. That might do a lot.
