The dynamic data that is driving the visualization needs to be accessible (fetchable) in alternative textual formats.

One possible way is to link to a dynamically populated data table using the @longdesc attribute. See http://dev.w3.org/SVG/profiles/2.0/publish/single-page.html (Embedding by reference) for more details.

Other methods would be to have a visual (on screen) link to the same data-table
