Flare Flare is an ActionScript library for creating visualizations that run in the Adobe Flash Player. From basic charts and graphs to complex interactive graphics, the toolkit supports data management, visual encoding, animation, and interaction techniques. Even better, flare features a modular design that lets developers create customized visualization techniques without having to reinvent the wheel.

Protovis

Protovis 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. Protovis is free and open-source, provided under the BSD License. It uses JavaScript and SVG for web-native visualizations; no plugin required (though you will need a modern web browser)!
Processing.js 1.4.7 released! Since our last release, 1.4.1, Processing.js has been given a bit of a source code overhaul, culminating in a new release: 1.4.7! This release adds in new functionality that you might already know from Processing 2.0, but was missing in Processing.js such as new methods in PVector and XML. The release model has also been changed: we're going to be releasing a new version every time a merge in a patch that either fixes something, or adds a feature that is still missing. Processing.js

Raphael

What is it? Raphaël is a small JavaScript library that should simplify your work with vector graphics on the web. If you want to create your own specific chart or image crop and rotate widget, for example, you can achieve it simply and easily with this library. Raphaël ['ræfeɪəl] uses the SVG W3C Recommendation and VML as a base for creating graphics. This means every graphical object you create is also a DOM object, so you can attach JavaScript event handlers or modify them later.
