Another weird idea for function visualization.
The sketch creates a list of random points, then draws circles around them as a function of the distance from the special point +. You choose the function, though I've preloaded it with some I liked.
g is how many pieces the window is divided up into for point placement. (Actually, g in x direction and y direction, so g^2 pieces).
dmn is the largest dimension, width or height.
N is the number of points.
Not sure what to do with this, so if you have ideas, let me know! Did you find a function with a pretty distribution of circles?
