Is this issue open, @schemon ? This is my first time contributing so I thought I would start with something simple to understand the process.. Can I pick this up?

Im also completely new to this project. I would hope someone with more experience could comment. However, I had spend time to google for how to show the plot. By adding the code it will be displayed by default. I would consider having the show call commented out by default since its anoying with the popup after completing this step.

This is only beneficial to display the image if you run this tutorial on your computer as a script. It is working as expected in Colab. I'm not entirely sure we need to add this but if we do, it should be commented out with a note like this:

# pyplot.show() # If you are running this locally as a script and want to see the generated image, uncomment this line.
