 Cannot add dot executable to system path
When I run graphviz

I get the following error

graphviz.backend.ExecutableNotFound: failed to execute ['dot', '-Tpdf', '-O', 'test-output/aoc.gv.pdf'], make sure the Graphviz executables are on your systems' PATH

I don't know what the graphviz executables are. In any case, my best guess is that I have to add the path of the module that uses graphviz or I have to add the graphviz module to my .bash_profile. Currently, my bash_profile has this line:


So I tried adding the path of where the module that uses Graphviz is located which is


Plus the graphviz module itself which is:


Making the final product to be:


But that did not work. I need to know what string I have to add to the PATH.
This doesn't really seem like a Python question. Are you able to get graphviz working outside of Python, you're just having trouble with Python? Or have you not tried / can't get working graphviz by itself? Assuming the latter, you might want to take a look at
Feel like you're not getting the answers you want? Checkout the help/rules for things like what to include/not include in a post, how to use code tags, how to ask smart questions, and more.

Pro-tip - there's an inverse correlation between the number of lines of code posted and my enthusiasm for helping with a question :)
Problem solved. It took me a while to figure out that I had to download some non-pythonic software before I could get the pythonic software to work.

brew install graphviz

Was step 1 and I had done that before but I was getting an error message. It told me to change ownership of some files so I did that. Then tried

brew install graphviz

again and that did the trick.
