One of the things that bugs me about our oh-so-cool information revolution is this: We show such little imagination in how we actually look at that information. Think about it. We have all this fascinating data at our fingertips and yet we have decided the most effective way of viewing it is in…a table. Or a chart. Or a list of search results (“1.7 gazillion matches — click here for next 10 results”).

There has to be a better way. And actually there are lots. One of the best is the treemap. A treemap is a bunch of squares, arranged to form a mosaic. The size and color of each block mean something.

Here is an example.
