Joe (@szac) turned me on to Flot for a project he’s working on.  I’m helping him out with some php logic.  Flot a pretty nifty graphing library all in javascript.  The examples show that it’s capable of a lot: multiple axes, multiple series, highlighting, and all can be updated real-time using Ajax.  But at its simplest — give it some properties, a data set, and it’s off and running.  Actually forget the properties, it will compute a logical set of axes for you if you want.

That Flot does all of this in javascript (via canvas painting) is all pretty amazing to me.  To me, javascript is still what you use to make those mouseover nav links that change state.  My javascript chops never really progressed beyond the web circa-1998.
