Is there a good interactive 3D graph library out there?

Question

I'm looking for a library that will layout and display graphs (i.e. network diagrams, not charts) in 3D, with some interactivity like selecting and dragging nodes, rotating the display etc. I would like to do this in a web page so Javascript or Flash are preferable, I'd also consider Java.

Having looked myself I realise the options are very limited so I'm interested to hear of any such libraries regardless of language or interactivity, even if they don't run in a browser. 3D is essential though, there are other questions on this site convering 2D libraries.

Update: please, stop adding details of 2D graph libraries. As the question states, I'm only looking for 3D libraries and there are other questions covering 2D graphs.

Pros: great looking interactive 3D graph library, in Java.

Cons: not actively maintained, last update in 2003.
