I have not closely examined graphs produced by Braille embossers.
How well does en embosser produce a "smooth" curve, as, for example,
a parabola? It is in making this sort of drawing that either
a vibrating stylus or spur-wheel shines.
Although Steve's points are valid, for me, the lure of really good
raised-line drawings using dots produced by deforming the paper or
other medium taking the drawing is too strong to dismiss lightly.
