Can't install visualization dependencies on mac

[irisdyoung]

I can't install the visual dependencies on mac (13.5.7). Installing coloraide worked fine for me, but python -m pip install pygraphviz or python -m pip install 'automata-lib[visual]' does not. I get:

Failed to build pygraphviz

I overwrote my system python with a homebrew installation some time ago so I grabbed a fresh python directly from python.org in case it mattered. That version, a homebrew installation, and a miniconda installation all produce this error for multiple versions of python (3.8 through 3.12, haven't tried all combinations in between; pip 24.0 for python 3.9 and pip 19.2.3 for python 3.8).

I think this error comes up if you don't have graphviz installed. Pygraphviz is basically Python bindings for the graphviz package: https://graphviz.org/download/

Alternatively, if you use conda you can install graphviz (and pygraphviz) in a conda environment.

[irisdyoung]

Sure enough, with graphviz there first they all work.

I'll add a note to the readme about this, since a couple of people have reported seeing this error message.

@eliotwrobson Just checking in to ask when you'd be able to add a note to the README about this installation gotcha. I think as soon as it's added to the README (even on develop), we can close this ticket.

[eliotwrobson]

@caleb531 makes sense! I added the note in #217. I marked it as draft to wait for responses by the original issue creators, but I think it's been long enough we can just proceed.

The changes there are in a complete state, so I'll go ahead and mark it as ready for review. If you think it looks good, I say we merge and close the open issues 👍
