Javascript, visualization and statistics (Protovis and Jstat)

Last week I got faced with two very interesting libraries.

Protovis uses JavaScript and SVG for web-native visualizations. Protovis composes custom views of data with simple marks such as bars and dots.

Unlike low-level graphics libraries that quickly become tedious for visualization, Protovis defines marks through dynamic properties that encode data, allowing inheritance, scales and layouts to simplify construction.

jStat is a statistical library written in JavaScript that allows you to perform advanced statistical operations without the need of a dedicated statistical language (i.e. MATLAB or R).

Read Write Web has also an article about other 20 JavaScript Libraries for Data Visualization
