"""
Draws a beach ball diagram of an earthquake focal mechanism.
S1, D1, and R1, the strike, dip and rake of one of the focal planes, can
be vectors of multiple focal mechanisms.
:param fm: Focal mechanism that is either number of mechanisms (NM) by 3
(strike, dip, and rake) or NM x 6 (M11, M22, M33, M12, M13, M23 - the
six independent components of the moment tensor, where the coordinate
system is 1,2,3 = Up,South,East which equals r,theta,phi). The strike
is of the first plane, clockwise relative to north.
The dip is of the first plane, defined clockwise and perpendicular to
strike, relative to horizontal such that 0 is horizontal and 90 is
vertical. The rake is of the first focal plane solution. 90 moves the
hanging wall up-dip (thrust), 0 moves it in the strike direction
(left-lateral), -90 moves it down-dip (normal), and 180 moves it
opposite to strike (right-lateral).
:param facecolor: Color to use for quadrants of tension; can be a string,
e.g. ``'r'``, ``'b'`` or three component color vector, [R G B].
Defaults to ``'b'`` (blue).
:param bgcolor: The background color. Defaults to ``'w'`` (white).
:param edgecolor: Color of the edges. Defaults to ``'k'`` (black).
:param alpha: The alpha level of the beach ball. Defaults to ``1.0``
(opaque).
