Generating an animation by calling pause between plotting commands.

The method shown here is only suitable for simple, low-performance use. For more demanding applications, look at the animation module and the examples that use it.

Note that calling time.sleep instead of pause would not work.

Generating an animation by calling `~.pyplot.pause` between plotting commands.

The method shown here is only suitable for simple, low-performance use.  For
more demanding applications, look at the :mod:`animation` module and the
examples that use it.

Note that calling `time.sleep` instead of `~.pyplot.pause` would *not* work.
