This is a demostation of FMChart, a system to dynamically generate accessible web charts.

The JS file is available at http://0xj.info/js/graphs.js. If you are looking for usage reference, you can check these blog posts (in Spanish): basic reference and pie charts reference, or an article at WebDevNews (in English). You can always download this demo as well.

FMChart is mainly based on ECMAScript (a.k.a. JavaScript), and currently supports pie charts and bar charts. For bar charts it uses HTML elements combined with CSS, to generate attrative and readable charts that are viewable by accessibility users by means of the HTML DOM tree produced. For the pie charts, the CSS and HTML power is combined with SVG or VML (depending on support) that provide with an adequate medium for drawing the pies. They, however, retain the accessibility offered by HTML.
