JFreeChart is an LGPL charting library for Java that got mentioned on the SQuirreL SQL users' list today. Neat. Don't know that I'd need it in my isql client and haven't had time to look at it in action, but neat n'ertheless.

Turns out SQuirrL was its author's first cut at using Swing. There are a couple of aggravating navigational bits, but overall it's, as I've said, excellent. I use it daily. Now if I'd just get off my duff, release my trialware app, and make a VIm plugin for it.
