I made this data visualization of lobbying data for my ICM class. It was due yesterday at 9:30am, and I turned in a much worse version of this, because I'd wasted a bunch of time messing with a deprecated Sunlight Foundation json method. In the end, I just downloaded 200MB of lobbying data from OpenSecrets.org and used the awesome, new Google Refine to clean up the data before writing my Processing sketch.
Edit: Sam points out that I had cumulative totals, not the actual industry totals. Fixed
