I’ve already blogged about graphical social network visualisations for boards.ie; I’m now adding to my wiki the scripts used to pre-generate the XML for Prefuse graphs of these networks (i.e. user networks of vBulletin mutual buddy links). These are similar to those used to visualise the blogosphere on Planet Journals as well (just using blogroll links instead of buddy links).
