Installing pygrahviz in google colab

In order to install graphviz, one can follow, this example: https://colab.research.google.com/drive/1_Qb92Hj5_f2rpta67JC0JKXwE2581Ar-#scrollTo=BOa9gIcDo6GS

When I try to install pygraphviz (https://pygraphviz.github.io/) via (https://pypi.org/project/pygraphviz/)

with 

!pip install pygraphviz
import pygraphviz as pgv

i get the error 

ERROR: Failed building wheel for pygraphviz

although I installed graphviz before. Why?

Though the answer by @korakot solved the issue, but it does not address the issue of installing pygraphviz library in Google Colab.

If you have to do install pygraphviz in Google Colab then the following worked for me.

# graphviz is installed already, but need lib too
!apt install libgraphviz-dev
!pip install pygraphviz

I found this solution here: https://gist.github.com/korakot/a80c04a1945b06e2f4a053f92fecfbf9

You don't need to pip install anything.

Just import graphviz, not pygraphviz.

My minimal example:
