Flick your Photos With Flickr Graph

Does Flickr bring people together? Yes anyone that has visited knows that. Strangers from far corners of the world sharing what their cameras caught and commenting on photos, creating groups and teams, both public and by invite only. But I found the Flickr graph which allows you to explore those relationships that exist within Flickr.
In my research about social networks, I have seen other methods that explore relationships withing groups like MySpace or even yahoo email. This also uses classic attraction-repulsion algorithm for graphs and I have no clue about the algorithm as he explains.
This is not a new application and has been running for while, since 2005.
Go have a look.
