Feedback for the authors: I had a really hard time finding the "graph_boundaries" code (I eventually saw the "Click to show" button on the right)

I love the source code included, very handy for the future!

Thanks for the helpful feedback. I wanted to put emphasis on the graphs so I chose to hide the code but maybe it's not worth the cuteness of the "click to show". Changing that now.
