OK, I've come to terms with fact that I'm not going to have any time to
work on this for a couple of weeks, so I'm shipping a part-baked demo to
see whether anyone reckons it's worth pouring a bit more effort into.

This was a late night Perl scripting hack-job last week, but I'm pleased
with what it does, though not how I did it. It turns out that AT&T's
GraphViz (http://www.research.att.com/sw/tools/graphviz/) toolkit can do
a pretty good job of laying out a visual representation of directed
graph structures, and that transforming RDF graphs into the .dot graph
description format understood by GraphViz is quite easy (though harder
to do well). So, I made a web-based RDF visualisation service using the
GraphViz plus the W3C Perl RDF parser http://www.w3.org/1999/02/26-modules/ 

Disclaimer... disclaimer... (don't forget to read the privacy warning,
your data graphs will be dumped in a public web directory and world-visible) 
and that if the parser finds errors, the whole thing will crash and
burn.

All that said, let me know what you think. I've more ideas for what we
might do with this than time to do them (eg. aggregation demos pulling 
stuff from multiple URIs, colouring the graphs to indicate provenance,
VRML or SVG output etc etc... -- possible student projects?)

Anyway, RDFViz online demo:
