|Gregable's Facebook Social Graph - click through see a larger version.|
Each vertex is a friend of mine on facebook. There is an edge between two friends if they are friends with each other. I'm not actually in this graph, otherwise there would be a vertex with an edge to every other vertex.
I called out my wife, Cristin, who bridges several regions of my graph. Even without me calling out that node, it would have been easy to guess.
The green region is high school. The blue region includes Google employees, which is naturally over-represented. College gets broken up a bit, and I wasn't really using facebook much for keeping in touch there. You can see some other dense clusters in here as well, but I'd didn't bother labeling them.
To me, this reinforces the Circles concept pretty well!
Parsing the pages was some hacky python and regex. Some of the templates weren't parsed as easily as others, so a few friends just got dropped due to laziness. Any friend who didn't have any mutual friends also got dropped. However, I didn't require a connected graph. That just happened on it's own, to my surprise.
The graph was laid out using neato, and then I added the colored boxes on top by hand using Gimp.
With neato, I can change a line and get the nodes as text boxes with names instead, which is fascinating to look through, but not something I feel comfortable sharing publicly.
Also note that I don't do a good job of maintaining facebook, and have had purge cycles many times in the past. A larger graph with a bigger picture would be even more fascinating I think.
