Animated graphs in ipython notebook

Question

Is there a way of creating animated graphs. For example showing the same graph, with different parameters.

For example is SAGE notebook, one can write:

If you use IPython notebook, v2.0 and above support interactive widgets. You can find a good example notebook here (n.b. you need to download and run from your own machine to see the sliders).

It essentially boils down to importing interact, and then passing it a function, along with ranges for the paramters. e.g., from the second link:

In [8]:
def pltsin(f, a):
    plot(x,a*sin(2*pi*x*f))
    ylim(-10,10)
In [9]:
interact(pltsin, f=(1,10,0.1), a=(1,10,1));

This will produce a plot with two sliders, for f and a.
