Question

Did I miss anything? Why can't the graphics be displayed even though all the required packages have been installed?

You did not install graphviz itself (pip install graphviz installs the Python bindings for graphviz, which is not a Python thing and thus needs to be installed separately).

I don't use a Mac and am not familiar with its packaging systems. https://graphviz.org/download/#mac has some suggestions.
