Data Visualisation & free 3D Graphing Tool

I've been to several talks over the past few months about Data Visualisation (DV) in SL ... so decided to build a DV display/exhibition in Int.Schs.Island.

This project went a little further than I anticipated ... I've also built a 3D graphing tool ... which I suspect may also have other teaching/learning uses rather than just DV ... it is free for you to take.
All in the lobby of the Technology Tower...
