Sounds impressive but not very useful for real analysis.

What about a general time axis (past to the right, future to the left,
but no real scale)?

Elasticity and tension could be used to make the linked objects to
cluster together. And if you want to find out what is related to
something, just drag it and watch what else moves.

You might be interested in NaviGraph by James Wen,
http://www.escape.com/~jimwen/naviGraph/naviGraph.html He has an
applet that shows his web in 3D, where the third dimension is used to
show a different kind of information than the other two. He has a
paper about it which might be interesting:

That would be great! Reminds me a bit of the technology graph in Civilization.
