Treemaps

I’ve been working on a new Treemap View for Tinderbox. Here’s an example:

What we have here is a section of a Tinderbox note file that contains lots of expense reports from a fictional business trip. Each expense is a box. The area of each box is proportional to the expenditure, scaled logarithmically. The color of each box is proportional to the number of words used to justify the expense to Accounting.

We’ve got more the fifty notes on view view here – more than we could get onscreen with a outline – and a nice mix of hierarchical structure, visualization, and clarity. Big documents reveal some interesting structure, too; here’s my weblog:

There’s a good deal of work remaining to do, but it’s shaping up nicely.
