This reminds me of the JavaScript InfoVis Toolkit, which includes similar graph visualizations but also a handful more: http://thejit.org/ http://thejit.org/ I've used it in the past to visualize the structure of Google Wave conversations, and intend to use it in the future to visualize related products. (Unless I use this one instead, of course :) I think that a graph interface like this shouldn't be the only way to get at some set of data, but at least for some people, it can be a really new and compelling way to explore it.
