This library just pushed JavaScript to the top of the "to learn for real" list for me. It looks like a great tool.

You might also want to checkout another supercool JS visualization framework - http://thejit.org

I would love to be able to use Protovis but as an SVG-only toolkit it is not very practical if you have to provide a good experience to MSIE 7 & 8 users - see http://multimedia.journalism.berkeley.edu/tutorials/protovis...

(Yeah, I know, if they wanted a good experience why would they use IE7? But I think we have to live with IE8 for a good while.)

I've been working with Protovis for about 9 months now and it is a pleasure. It took a while to get my head around its data model, but once you do it is incredibly powerful. (IE is not an issue in my environments)

See also d3, a newer visualization framework from the same primary author. Similar to protovis but with a greater focus on updating and animation.

I'm looking through the source, specifically the jsDoc comments. Does anybody know what "[v]" means in this context:

     * @param {function} f function to execute on each value in the array.
     * @param [v] object to use as the first argument to the first call of

As I understand it, the parameter type is specified with curly brackets, like, "{function}" in the line above.

Thanks! But I can't find which browsers it supports, or which features it supports per browser.

Awesome, thanks for posting. I didn't know about this lib.
