FlickrGraph is a great new Flickr third party app by Marumishi, aka Marcos Weskamp.

Flickr Graph is an application that visualizes the social relationships inside flickr.com. It makes use of the classic attraction-repulsion algorithm for graphs. Start exploring your contacts by entering your flickr username or the email address you used to register there.

Be sure to doubleclick through on the member’s icon to see a view of their latest photographs, as well as links to the tags they use most frequently. It’s a really lovely way to surf Flickr.
