Life of CitiBike

This repository contains various files that I generated as part of my quest to animate the daily and/or weekly lifecycle of New York City's CitiBike system. All of the scoping, done in Python using Jupyter notebooks, is here, as are various toy datasets generated along the way, and—critically—the scripts which generate the visualization's backend. The only thing not in this repository is the final visualization itself, which is optimized for and hosted at my personal website, and can be found there.

If you are interested in following along, read this technical blog post first. Then, if you're still interested, start reading the materials in the notebooks folder.

Note that station depots and New Jersey locations (on which no data is yet available, annoyingly) have been removed from this dataset during processing.
