jQuery Heatmap?

Question

I've been looking for a while for a jQuery or JavaScript heatmap that looks close to this:

Infovis has a Treemap, but those borders within each box is annoying/not what I'm looking for. I'd prefer to stick with a language that I'm familiar with, javascript, jQuery, Perl, but willing to expand if the solution is out there.

Note: I've been told "R" language can do this, but this might be overkill for the dataset I have. Example dataset could be States for each box, size based on population, and color based on unemployment rate (not to be too dramatic).

Any ideas would be appreciated. Thanks

What about this example from the JavaScript InfoVis Toolkit ( http://thejit.org/ )? http://thejit.org/static/v20/Jit/Examples/Treemap/example1.html
