Canvas Charts Based on HTML 5 Table Data

This is a REALLY NICE looking jquery plugin. It makes visualization on the web really simple.

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. We’ve now rewritten and extended the code behind this technique and packaged it up as a new jQuery plugin called “visualize”, which you can download below. The plugin provides a simple method for generating bar, line, area, and pie charts from an HTML table, and allows you to configure them in a variety of ways.
