==================
Rotating a 3D plot
==================
A very simple animation of a rotating 3D plot about all three axes.
See :doc:`wire3d_animation_sgskip` for another example of animating a 3D plot.
(This example is skipped when building the documentation gallery because it
intentionally takes a long time to run)
