Tool: JavaScript InfoVis Toolkit

JavaScript InfoVis Toolkit (http://thejit.org/)is a tool that creates interactive data visualizations for the web.
The toolkit implements bar/pie charts, sunburst, icicle, directed graphs, treemap, spacetree, rgraph(round graph), hypertree, etc. The demo for each representation is available online at http://thejit.org/demos/.

In 2010, the project was acquired by Sencha Labs and the main author is Nicolas Garcia Belmonte (http://cv.thejit.org/). Fortunately, it will remain open source with a BSD license and anyone can contribute to the code.

The real examples used by the organizations are the White House (http://www.whitehouse.gov/winning-the-future/interactive-budget) and the Mozilla Foundation (http://www.mozilla.org/community/). The interactive budget treemap shown by the White House shows where the tax dollars goes to, especially, what percentage of the Federal Budget goes to different programs for 2012. Over 100 Mozilla's sites are shown with a hypertree which a click on a labeled node(site) would move the tree and center the clicked node with related sites surrounding it.
