Why not have an accompanying paragraph that describes the data in the
chart? It would be useful to all users, would fulfill the requirement
of alternative text, and would make the contents of the chart
indexable by search engines.

Mike's suggestion

I like to present the data from graphs in tabular form. The tables are
accessible and also provide the data in an alternative format that may
be more useful to many people. You can either link from the graph to the
table on a separate page or present the table immediately before or
after the graph. The alt text for the graph can be fairly simple at
that point. "Pie chart depicting racial distribution of consumers"
