| 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) | |
