gRaphaël’s goal is to help you create stunning charts on your website. It is based on Raphaël graphics library. Check out the demos to see static and interactive charts in action.
gRaphaël currently supports Firefox 3.0+, Safari 3.0+, Opera 9.5+ and Internet Explorer 6.0+
A simple to use, yet robust library for transforming table data into a chart. This library uses the HTML5 tag and is only supported on browsers other than IE until ExCanvas gets proper text support.
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.
The focus is on simple usage (all settings are optional), attractive looks and interactive features like zooming and mouse tracking.

ProtoChart is a new opensource library using Prototype and Canvas to create good looking charts. This library is highly motivated by Flot, Flotr and PlotKit libraries.
The plugin is compatible with most modern browsers and has been tested with Firefox 2+, Safari 3+, Opera 9, Google Chrome and Internet Explorer 6, 7 & 8.
