Canvas example with proposed accessible fallback for Bar Charts

Here is a link to a draft example of accessible fall back content for the canvas element when the canvas content represents a chart:

http://devserv.dres.uiuc.edu/ita/jongund/citaweb/test/aria/canvas/canvas1.html

This demonstration uses the data used to generate the bar chart to create an accessible data table. The table then is added to the document as a child of the canvass element.

Issues

    * Needed to add additional labeling properties to theRGraph libary for labeling data series
    * Does not work with the IE, since the VML generated by the canvas emulator plug-in is deleted.
