diagram of groups with the software Omnigraffle
In the amazing Flickr website, the "groups" area is a mess. Why not clean it up with some nice diagrams which show the hierarchy and links between each groups?
That software can compute automatic layouts, whatever the complexity of the diagram. It is specially useful in the case of an non-hierarchical one. Connexions between groups let it look like a "rizome" stuff.
In order to access conveniently the nodes, I generate a pdf file with direct access via weblinks : work in progress!
