Re: ARIA Graphics Module -- proposed roles hierarchy & data properties

The underlying principle which comes to mind here is that the user agent/assistive technology should perform the analyses that an informed observer could intuitively and easily carry out by inspecting the data as visually presented. The level of accuracy should be the same as what an informed recipient of the visual representation would be able to achieve.

Of course, if the author provides the actual data (as we’ve proposed to allow but not to require), then more accurate analyses can be undertaken.
