Issue with `plot_gos()`

[stefan-dam]

Hi there,

I was trying to use plot_gos(), but I got an FileNotFoundError:

FileNotFoundError Traceback (most recent call last)
File ~/opt/anaconda3/envs/test/lib/python3.9/site-packages/pydot.py:1912, in Dot.create(self, prog, format, encoding)

1915 working_dir=tmp_dir,
1916 )
1917 except OSError as e:

...
-> 1922 raise OSError(*args)
1923 else:
1924 raise

FileNotFoundError: [Errno 2] "dot" not found in path.

Could you please help me to fix this?

PS: I am using MacOS. As suggested in #170, I checked to be sure that I installed the Graphviz's dot program.

Thank you for your interest in GOA tools and for the great question.

On the command line, when you do dot -V, do you see a version of dot?:

$ dot -V
dot - graphviz version 2.50.0 (20220216.1147)
