The visualisation here is a pivot graph showing the number of tags used for each site in the folksonomy. On contemporary browsers, each graph has a link that lets you "pivot" between tag, users and sites as a way to help explore the folksonomic relationships. The visualisation uses "Scalable Vector Graphics " to create the visualisation. This works under Internet Explorer 7 and Opera. Tthe pivot link is not shown when using Firefox because Firefox does not fully support the format.

This model was produced by Dave Everitt and Ben Daglish. Some other interesting folksonomy visualisations can be found on Well-formed Data and via IBM's visualiser - Many Eyes.
