Exception when generating image about mossum HOT 5 OPEN

Just to make things clearer. As @zdzc mentioned you should install graphviz using your package manager. I was stuck trying to install graphviz using pip.

sudo apt install graphviz

from mossum.

I had the same problem earlier. Installing graphviz fix the problem for me.

Is there a way to get around this without needing to install graphviz through brew/conda? I'm having the same issue on Mac and I need to avoid using homebrew/anaconda in the file. I found the pip version of graphviz doesn't work either.

@FlynnMc No, not that I am aware of.

You can just download it, compile if necessary and add it to your path.
