I kept running into these polar "street orientation" charts on data-visualization subreddits and wanted to make one for the cities closer to home.

I built this chart inspired by some posts on Reddit, by modifying this osmnx example. For the city list, I took all the cities having a population greater than 75k from Wikipedia.
