[BlindMath] Any Affordable Tactile displays to analyze graphs and charts

[george at techno-vision.co.uk]

Hi David,

The Canute makes no claims about displaying graphics.

It's very much WYSYWIG. (What you see, is what you get)

Nor is it for all braille users.  But it is ideal for specific subjects
where braille layout is important.

The Canude is a multi-line display, but the lines are separated by some
space, so I don't know that you would get a coherent picture -- even if it
displayed graphics -- and I don't know if it can do this.
