A “curvature comb” is a type of graphical diagram added to the plot of a curve which shows a number of “teeth” segments with their bases along the curve, oriented perpendicular to the curve and proportional in length to its curvature. Personally I find it is easier to interpret a solid curve vs. a collection of line segments. But eventually I might also add a more traditional comblike display. I apply a sigmoid function (here, an arctangent) to the curvature so that even for very extremely sharply kinked cu

I've recently been learning about how to draw smoother curves that look more appealing. A common technique in professional CAD and font design software is to use a visualisation called a curvature comb to see how sharp or flat a curve is along its path. Here's an example of a curvature comb being used in Fontlab VI to smooth out bumpy spots in a font:
