[Blindmath] Graphs

[Suman Rath]

Hi all,
I am doing a lot of statistics and to understand a few concepts and
only for understanding, my professor wanted to draw graphs for me.
We were thinking of using the Intact sketchpad.

I had a few questions about it though.
1. Does it work well for drawing out graphs and curves?
2. Can a sighted person use a normal printed graph sheet underneeth
the main drawing paper for tracing purpuses?

Thank you for your help and advice!

Warm Regards,
Suman.
