Charting Day - Researching FREE(ish) charting libraries

I'm finishing off my day looking for a FREE (or cheep) charting libraries for one of our applications to show off our pretty data (I'm very proud). I'd prefer not to end up on any chartjunk websites so I better do this right.

Some contenders:
Flot – Flot is a pure Javascript plotting library for jQuery. The focus is on easy usage , attractive plots and interactive features. With Flot you can interact with the data, look at specific data by zooming in, plot a time series, and other various options.

JSCharts:

http://www.jscharts.com/how-to-use shows how to use .xml docs as data source, very clean

Sparklines: Gotta love them! This jQuery plugin generates sparklines (small inline charts) directly in the browser using data supplied either inline in the HTML, or via javascript. I guess I should know what jQuery is but to be honest I don't.

XML/SWF Charts: here's one that would cost us $50 for a single domain or $600 for the bulk license. Looks like you feed it XML to make the chart, then we could use whatever application software we want to generate the XML.
