Hi Amelia,

I would support making a richer taxonomy and would support building a
jQuery widget for exploring data visualizations. I would really like to get
a haptic tablet and see if we can make graphics touchable and work with a
screen reader.

If we can show a benefit for adding ARIA markup on graphics, I believe
folks that create charts will be willing to add markup to business and
scientific charts.
