[Blindmath] Reading graphs and diagrams with sound

[Michael Whapples]

I also agree that sometimes simple solutions are the best.

Also in the learning process its sometimes better to do things manually 
then one understands how the graph is created, not just how one uses a 
software tool to generate a certain chart. I know similar approaches are 
taken for other things (eg. when I was taught statistics I was taught 
how to calculate standard deviation for a set of numbers, although 
calculators have features for doing this for you).

Also I personally feel that as normally a tactile version of the diagram 
relates closer to the visual chart someone would have, it can make it 
easier for communicating ideas relating to the chart.

Once an understanding of the basics is mastered then using computers may 
help, but at least one understands what is going on and possibly will 
pick up when the computer gets it wrong.
