I am teaching a module related to data visualization. Thus, of course, most of the tools are visual tools, that is, tools for visualizing summaries of the data.
I have visually impaired students, which makes it really difficult to teach them these tools, as it involves two- and three-dimensional plots and graphs.
Creating an audio substitute for these is very complicated, but of course it is essential to make the teaching material available.
What are the main rules for making this kind of material accessible?
