basic question

I just want to see my figure displayed in a Tkinter window,
without using pylab, with no extras.
No other goals right now.

Is
http://matplotlib.sourceforge.net/examples/embedding_in_tk.py
essentially a *minimal* example of how to do this?
(Aside from the title and toolbar stuff.)
This is a completely naive question.
E.g., choice of backend never implies that we can avoid
explicitly embedding, as this example illustrates, right?

Thanks,
Alan Isaac

PS What happened to the object oriented "intro" that was
linked from the Matplotlib page for awhile? Or did I just
overlook it?
