this is a sketch based on paris subway network. it's mostly an infrastructure to play with - an oriented graph with stations, and classes to interact with it. I haven't done anything terribly impressive with it though, but maybe I will (or someone else will!)
anyway, I've included the painstakingly assembled data in the zip. Also, the stations x and y positions on the screen have been pre-computed, I think my projection is a bit off, so I've included their longitude and latitudes.
It doesn't seem to display right now on openprocessing but can be downloaded alright.
