ipython display figure

[Stestagg]

I'm guessing here a little bit, but it looks like the author expects you to
run this code in a jupyter notebook, rather than in an ipython interactive
console.

The jupyter and ipython projects are related (the same?) which can cause
some confusion, but if you run the code you shared in a jupyter lab
environment, then the SVG should display.

As an example, you should be able to view the expected SVG in the following
google colab book:
