From an article caption: The coordinate surfaces of the spherical coordinates (r, θ, φ). The red sphere shows the points with r=2, the blue cone shows the points with θ=45°, and the yellow half-plane shows the points with φ=−60°. The z-axis is vertical and the x-axis is highlighted in green. The

Nominating as a set for various coordinate systems. Could narrow this down to the first three (which are the most common in practical use) if need be as I don't think Oblate spheroidal coordinates are particularly common beyond mathematical
201:
three surfaces intersect at the point P with those coordinates (shown as a black sphere); the
Cartesian coordinates of P are roughly (0.707, −1.225, 1.414). So in each case the point is given by the intersection of the surfaces.

This could be an easy SVG target, and can be vectorized to much cleaner versions as MER-C mentioned. Maybe request at
