I finally did it!
The city of Boston recently released their data in the open. I wanted to have an excuse to play with geospatial data, so as a distraction from thesis & proposal writing, I hunkered down for about a workday's worth of time and put together a bokeh app.
In this web app, the end user can select from one of a number of geospatial datasets released, and visualize the distribution of those data points. There's no added metadata right now, but if I get fed up with thesis & proposal writing I might go back and add in metadata hover/tooltips.
I hope you have fun cloning the repo and running it!
