Hi Sean, I've never seriously used these: - http://hypergraph.sourceforge.net/ - http://hypertree.sourceforge.net/ but if you want to give it a try, pick one (or both), write a small "hello world" example (a tiny graph/tree of a few nodes/links will do) and share it somewhere on GitHub. I can easily add the loading from TDB indexed to it. I am a bit skeptic on how it would work at scale, but hyperbolic trees [1] have a good visual property that things a few hops away are very small, up to a point that you do not even need to show them. Therefore something like an extended CBD (i.e. the CBD of the subject you are looking at, plus the CBDs of things one or two hops away) would probably do. It certainly is a first initial step to see if it actually works and check it's useful. Maybe others are interested as well... Paolo [1] http://en.wikipedia.org/wiki/HyperbolicTree
