How to make complex statistical graphics accessibility
We develop and test procedures that make documents more accessible and understandable for all users. When possible, we go beyond the minimum that's required by law and provide a better experience for those using assistive technologies.
When designing statistical graphics, we plan the entire "package" of information that includes not just Alt-Text, but also the nearby body text, prefatory text, and matching data tables.
Alt-Text is just part of the most effective solution.
