First attempt to the installation failed because of missing graphviz:

(django_python_env) MBP:mysite jhartman$ pip3 install pygraphviz

Ok, so next obvious step was to install missing library using brew:

Everything looked find, however pip’ing still shown same problem with not installed library. I think the reason was in the warning show above:

In order to prevent conflicts with Apple's own libtool we have prepended a "g"
so, you have instead: glibtool and glibtoolize.

Ok, so where we have eventually the lib?

MBP:~ jhartman$ find /usr/local/Cellar/ -name "*graphviz*"
/usr/local/Cellar//graphviz
/usr/local/Cellar//graphviz/2.40.1/.brew/graphviz.rb
/usr/local/Cellar//graphviz/2.40.1/include/graphviz
/usr/local/Cellar//graphviz/2.40.1/include/graphviz/graphviz_version.h
/usr/local/Cellar//graphviz/2.40.1/lib/graphviz
/usr/local/Cellar//graphviz/2.40.1/share/graphviz
/usr/local/Cellar//graphviz/2.40.1/share/man/man7/graphviz.7

So we’re almost there. Let’s convince pip to use include and lib folder mentioned above (by enforcing it by --install-option):

(django_python_env) MBP:mysite jhartman$ pip3 install pygraphviz --install-option="--include-path=/usr/local/Cellar/graphviz/2.40.1/include/" --install-option="--library-path=/usr/local/Cellar/graphviz/2.40.1/lib/"
