If you're using or developing #JavaScript libraries that are used to display charts and diagrams, this new #WAI-ARIA module brings new roles (i.e. markup annotations) that can help make their content more accessible - make sure to check them out!
The #ARIA Graphics module adds a few additional recognized roles to help annotate complex graphical content, e.g. labeled diagrams or interactive graphics. w3.org/TR/graphics-aria-1.0/
The ARIA Working Group is seeking feedback in its repo github.com/w3c/graphics-aria… on these new roles.
