Here’s an interesting way of visualising data – Many Eyes from IBM. You can upload data and produce graphs in all kinds of different forms – beats the hell out of Excel. There are the usual graphs and also other ways of representing texts, like word clouds/wordles. These make more common words larger, so it’s easier to see what the key words are in a piece of text. The other neat thing is being able to reorder data from the graph itself – handy when you have 3 axes.
