PR Summary

Since the area or size of markers in scatter is the area of a box the two examples modified in this PR were confusing as they defined the area as the area of a circle while stating in a comment the desired range of radii. With the previous definition of area the markers would only have a maximum of pi/4 times the desired area (sqrt(pi/4) times the desired radius). The new definition of area now agrees with their respective comments.

Perhaps to even better agree with the stated radii in the comments the edge patch should be disabled with edgecolors='none' in the call to scatter as the edge patch adds about 2 pixels to the radius.
