Here are some examples of the text equivalents generated the
Accessible Web Publishing Wizard for Microsoft Office [1]. 
The text tables are generated automatically by the Wizard and
put in-line with the html content. I would be interested in
people comments about the text table accessibility and putting
the text equivalents in-line with the graphical chart.
