JavaScript Information Visualization Toolkit (JIT) is an advanced JavaScript infovis toolkit that was based on 5 papers regarding different information visualization techniques. The JIT implements advanced features of information visualization like Treemaps (with the slice and dice and squarified methods), an adapted visualization of trees based on the Spacetree, a focus+context technique to lay Hyperbolic Trees, and a radial layout of trees with advanced animations (RGraph).

These are the different features of the JIT toolkit. It’s still on an alpha state, but it’s very well documented and on active development. The library consists on standalone libraries. That means at the moment you won’t be able to include more than one visualization library per page.

We have been waiting so long for Google Chart API. Google has finally released Google Charts API, which returns a PNG-format image in response to a URL. Several types of image can be generated: line, bar, and pie charts for example. For each image type you can specify attributes such as size, colors, and labels.

You can include a Chart API image in a webpage by embedding a URL within an <img> tag. When the webpage is displayed in a browser the Chart API renders the image within the page.

The chart above is generated dynamically and displayed in your browser with the following code.
<img src="http://chart.apis.google.com/chart?cht=p3&chd=s:hW&chs=480x150&chl=Large Portion|Small Portion">
Go and check out the developer’s guide of Google Chart API now.
