You can now edit automatically generated alt text. By default, Tableau provides automated screen reader text, ensuring there's a description to be announced by screen readers for all online visualizations, including client and server-side rendered and embedded visualizations. Now, content authors can edit the alt text from either the Data Guide panel or by selecting Accessibility in the Worksheet drop-down. Authors can add up to 2500 characters of alt text, providing deep insight into the contents of the visualization.
