I agree that there is a need for a consistent and predictable way of choreographing the timing of AT announcements, but I am less convinced that a fixed delay is...

A data table as alternative is very helpful, but only goes so far. Tables are typically poor at representing arbitrary **relations between parts**, such as the following: - supports/corresponds -...

I'm happy to compromise on the name! I agree that the point is not to remediate something visual, but to offer a first-class, presentation-agnostic alternative to a visualisation. Funny how...
