Charts and Graphs

Text browsers and screen readers cannot convey images to their users, so you should provide an alternative to the information that is visually available. This is especially important if you're displaying a useful chart or graph! Provide alternative text using the "ALT" attribute of graphics to summarize charts and graphs.

Use one of the following three methods to provide alternative summary text for detailed information contained in charts and graphs:

33.1. Surrounding Description Text
33.2. Description Link (D-Link)
33.3. Long Description (LONGDESC)
