An interesting little tool from Carrot Search, creators of Lingo3G, is a tool called ‘Circles’. It integrates JavaScript & Flash to create interactive hierarchical circle diagrams.
Carrot Search Circles is an interactive visualization of hierarchical data structures, such as groups of documents or network domains. It gives an instant overview of the structure and contents of the groups.
Be sure to check out the demos on their site.
