ALT text/ general accessibilty for JSX graphs

[Hayden Maudsley-Barton]

Hello! 

We use the JSXgraphs moodle filter, particularly in stack questions. I was just wondering if anyone has any advice/ experience with making these questions more accessible. Is there a way of adding alternative text? I am wondering if just adding a details tag with a long description could be the move; or if we would need to leave this to accommodations on a case by case basis as it can be complex. Any thoughts are appreciated.
