Social Network Visualization of the Presidents of the USA
I recently attended a MeetUp of the Los Angeles Semantic Web & PHP Meetup Groups. It was a presentation on the Factual API. Factual is a very cool company building a platform for “open source data.” I pulled down some data to test and created the following visualizations, which reveal…well, something about American Presidents. I’m not quite sure what that something is, but it’s interesting to me. What do you think?

Interconnectivity of Presidents Over Time
This shows the shared connections to universities & branches of the military over time. I have grouped them into groups of 5 presidents at a time, which are the ones highlighted in yellow. This is the most interesting case I found. The middle of the 20th century appears to be the least interconnected.

Presidents & Their Colleges / Universities
This is interesting because it is not, as I would have hypothesized, all Harvard and Yale folks. In fact, the Harvard / Yale crowd is most best represented at the beginning of the country and in the last 50 years. A lot of presidents did not attend college.
followup: State Money visualizations for California
As a followup to the last blog post on State Money in Florida, here are the visualizations I rendered from the State Money data on California:
Top donors with donation sizes indicated by link thickness; republican = red; democrat = blue.

Top Republican donors. One does NOT donate to Gov. Schwarzenegger.

Why does this guy support the one Democrat?
