No freakin' path
Installed Graphviz as it appears to be a great package. But it installs without creating a path to its location; thus, it's useless--except to those who know how to tinker with such things. Thus, it's useless to 99% of people. Now, after trying to add a path using online instructions nothing in Jupyter works. No libraries load; everything is hosed.
What is the problem with just simply setting the proper path with a software installation?
