RGraph: HTML5 & Javascript charts for your website

RGraph is a charts library written in Javascript that uses HTML5 to draw and supports over twenty different types of charts.

Visualize

Accessible data visualization in HTML has always been tricky to achieve, particularly because elements such as images allow only the most basic features for providing textual information to non-visual users. A while back, we wrote an article describing a technique we came up with to use JavaScript to scrape data from an HTML table and generate charts using the HTML 5 Canvas element. The technique is particularly useful because the data for the visualization already exists in the page in structured tabular format, making it accessible to people who browse the web with a screen reader or other assistive technology.

InfoVis

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)! Although programming experience is helpful, Protovis is mostly declarative and designed to be learned by example.

Processing.js

Processing.js is an open programming language for people who want to program images, animation, and interactions for the web without using Flash or Java applets. Processing.js uses Javascript to draw shapes and manipulate images on the HTML5 Canvas element. The code is light-weight, simple to learn and makes an ideal tool for visualizing data, creating user-interfaces and developing web-based games.

Processing.js is explicitly developed for browsers that support the HTML5 element. Processing.js runs in FireFox, Safari, Opera and Chrome but will not be supported in Internet Explorer until Mircosoft catch up with ISSUE 15.

The purpose of this script is to provide a unique and elegant way to visualize data using Javascript and the object. This type of visualization can be used to display connections between many different objects, be them people, places, things, or otherwise. The script is licensed under an MIT-style license.

This script requires three libraries to support it. CanvasText (for text support with canvas elements), ExCanvas (for IE canvas support), and MooTools 1.2; all three are included in the package. View the project on Google Code.
