pyplot animation

================

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.

Output generated via `matplotlib.animation.Animation.to_jshtml`.
