Question about images and d-links

[curtiss]

For the first time in quite a while, I had to add an image of a pie chart to one of my Web sites. In doing so, I needed to create a "longdesc" and d-link for the chart, to explain the item to any visually impaired visitors we may have.

Is it acceptable/usable to use a table within a d-link or longdesc page? Being that the image is of a pie chart, I thought that using a table to convey the information was acceptable. However, I am unsure of how usable tables are for visually impaired users, and I want to make sure I didn't add an extra hurdle.

The table is built properly, using a caption; thead, tfoot and tbody elements; th elements with the appropriate scopes defined, etc.

I just want to find out whether you guys think it's okay to use a table as the longdesc of a pie chart. If not, how would you recommend I present the information from the pie chart to our visually impaired visitors? Any thoughts would be greatly appreciated. Thank you.

Depends on your definition of "poorly supported". If you mean among Web developers, you're correct. Not a lot of Web developers are using the D-link. However, not a lot are using the longdesc correctly, either, so it's kind of a toss-up.

If you mean that it's poorly supported among browsers, then that's not true. The d-link is much more widely supported than the longdesc, apparently. From what I've been able to find out, most browsers have poor support for the longdesc attribute, but they all have support for links (which is why the d-link was created).

One of the videos I mentioned in this blog post mentions d-links and gives a good description of them.
