Link Visualisation

I have been having a thought - something to do with visualising the relationships between sites/blogs/posts/pages.

Clearly others have gone before me, I rather like:

http://www.touchgraph.com/TGGoogleBrowser.html, http://www.aharef.info/static/htmlgraph/ and http://home.snafu.de/tilman/xenulink.html for various reasons.

None of these quite do the job that I need - so if I'm going to create something myself I need some:

• network visualisation, including some de-cluttering algorithms
• site indexer (perhaps using web analytics data)
• source of link information for links going in the other direction

To be fancy this could all be done in 3D, but I'm not sure it would be any more useful than something in 2D.

And then I'll become fabulously rich.
