JavaScript InfoVis Toolkit 2.0 released

Visualization in JavaScript is all the rage these days. Just a couple of years ago, this would've seemed ridiculous because the engines were too slow, but no more of that. To that end, Nicolas Garcia Belmonte just released his JavaScript InfoVis Toolkit 2.0. It's got your treemaps, stacked area charts, pie charts, weighted graph, so on and so forth. You can see all the demos, plus code examples to get the full picture.

This is not dissimilar to Protovis from the Stanford visualization group. Although, I'm told the JIT is fully functioning in Internet Explorer. Protovis only partly works in IE right now.


  • Hi Nathan, thanks for taking the time to review the toolkit :) .

    I’d also like to add that the toolkit supports (to some extent) mobile devices and touch events. Also, although all visualizations can be used in IE some features are turned off (shadows and gradients, some smooth animations, etc), so I’d recommend to take a look at the demos with any other browser (Opera, Firefox, Chrome, Safari).

    Thanks again for the review :)
