Story: I as a blind or visually impaired student need to be able to access graphs that represent mathematical expressions

Sonification of graphs has been a useful accessibility and multi-modal delivery technique for blind and vision impaired students. Implementation and research has been done by NASA with MathTrax and Georgia Tech's Sonification Lab.

Sonification can be accomplished on the web platform with the Web Audio API. We have built a prototype at:

Screencasts:

We would like to generalize this prototype by having semantics in the SVG that indicate to the sonification JS code what the data, axis and tick mark elements are.

Requirement(s)
