Charting tools

Here's a rough overview of some graphing solutions, in no specific order. The purpose of this is to find a suitable tool to display patient and cohort data graphically. Ideally it should be:

FOSS
Cross-browser / cross-platform
Lightweight / Thin-client oriented
no need for special downloads
Good user community
Interactive and flexible
SVG, if possible

Feel free to add more alternatives and/or comments.

Dojo Charting Engine

Since OpenMRS already uses Dojo, this might be a good option. The repository does not include the charting libraries though.

Docs

Examples:

The good part:

FOSS
claims to be cross browser (need to check, my first test with IE7 failed to render)
uses SVG rendering when possible
javascript solution, which should make AJAX easy to use (need to check on this, example 1 seems like a good starting point)
can be altered to suit our needs

The not-so-good part:

no built-in pie charts
very few examples on the web. Good user community for Dojo but not so much support for the graphing engine
doesn't seem as complete as other solutions below
doesn't seem to provide a lot of interaction with the charts. Need to confirm this, but judging from the static examples, we will probably have to deal with interactivity ourselves.
