Grokker

Grokker has been on my radar for a while. I recently received an email about their demo service. While the visualization itself (hierarchical circles) is not completely novel, I love the fact that companies are more and more willing to expose users to novel rich client interactions with web data. I will write more on what I mean by rich client, especially with respect to the web, at a later date. For now, visit Grokker and play with the search demo.
