================
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`.
