Word maps generated by wordle.net have been making the rounds. They are very cool representations of the frequency that various words appear in a hunk of text (such as a blog feed). Unfortunately, the code to generate these word maps is not open source, and it requires Java.
If you’re interested in the code, a Mercurial repository is available on hg.mozilla.org. There are a couple improvement possibilities noted in the README file. Some other possibilities that I’m just thinking of now:
- Produce an image map to make all the terms link to the relevant post(s).
- Produce SVG output to make the output scalable.
