Would it help to have some kind of a reverse plotter?
Imagine an XY gantry like a 3D printer has. The axis are free, so the device reads the coordinates as the user moves them. It in turn has a little servo motor in there moving the "stylus" in the Z direction. When trying to view an image, white would be mapped to "down" and black would be mapped to "up". This would make it possible to "view" simple 2D plots, or perhaps even equations.
User experience could be improved by using force-feedback motors on the XY gantry, essentially nudging the stylus to stay on the line.
Something like this should be somewhat doable for about $200-300, I reckon.
Hard to say. Information density matters and also the speed with which one can explore the graph. The limited use cases also might make it impractical.
