Graphviz installation (Windows)

[profjpbaugh]

As a note to others in case you come across this issue:

The graphviz must be installed through Anaconda Navigator (Environments --> Search for All or Uninstalled packages --> graphviz).

At least, this was my experience on Windows. Installing it via pip is not sufficient.

Thanks for your message. Indeed, that's why environment.yml contains two lines:

  - graphviz  # used only in chapter 6 for dot files
  - python-graphviz  # used only in chapter 6 for dot files
