San Francisco Film Locations

I was looking for a fun open data set, and came across this one about film locations in San Francisco.  

The chart type is called a 'bee swarm', and I've combined them into small multiples here. It was fun to work on.

This is just my first draft data visualization. I hope to have time to come back to it and play with it some more.

The source code, and interactive version, can be found here.
