I remember it being a Java applet with animations, but my memory could be terribly faulty at this point.

Following your comments and trying to trail things out, the only thing I can find is a reference to AltaVista LiveTopics.

I suspect what I used was that "GRAPH" button in the AltaVista Refine picture.

We might want to archive that image. It seems like the only evidence that this stuff ever existed.

which has some different coverage.

I did try to archive the blog you linked but unfortunately the owner is blocking it with robots.txt

That hyperbolic tree looks very close to what my faulty memory recalls.

I suspect it was a later incarnation that I used.
