My two ideas for a final project are...
Foursquare Knows You
An interactive data visualization of your Foursquare check-ins. This would build upon my 2nd assignment, which visualized my Foursquare check-ins based on venue categories. The website would let users log in with their Foursquare account so they could visualize their own data - if they don't have a Foursquare account, they can just use my data.
Secret Drone Strikes
An interactive data visualization of drone strikes, provided by data from the Dronstre.am API. I like maps, so I'd like to create a visualization where only the three countries covered by the API (Pakistan, Yemen, Somalia) are visualized somehow by their accompanying data. The rest of the world is opaque/invisible.
