Gelphi is a reasonably simple and interesting tool for visualisations. Here is a blog post by Tony Hirst about how to use it, and below is a video introducing it. You might also check out the (385 and rising) delicious tags at http://delicious.com/ibbertelsen/visualisation.

very useful indeed. Alright, I am now going off to plunder yr 385 ( and rising) links on delicious! It will inspire me while I’m writing the lecture for wed.
I am really looking forward to our Visualisation part of the course. So much stuff to talk about, and so much stuff to look at!
