simple thing combining a sort of sparkline with some visual concepts from Armelle Caron's beautiful tout bien rangé project.
It'll hopefully result in a simple visual phrase for given city blocks, showing the form of spaces created by street layout.
The repo has some development tiles from Stamen (toner-background) checked in. Otherwise the canvas
getImageData has some kind of same origin policy, server.js is mostly for proxying
remote tile providers.
To use:
node server.js // http://localhost:8002
