"graphviz" dependency appears to be specified incorrectly

tributary does import graphviz, not import pygraphviz, so I think that:

  • in pip land you need to pip install graphviz and also make sure you have the actual graphviz installed (e.g. via your system package manager or whatever)
  • in conda land you need to conda install python-graphviz (which itself depends on graphviz).

The other package here is pygraphviz, which provides the python module pygraphviz. Although that's listed in the dependencies of tributary, I think it's unused. Which is lucky, because the way pygraphviz is specified in setup.py (following on from the pandas dependency, which is missing its trailing comma), it doesn't get installed. Which is lucky, because pip install pygraphviz (and hence pip install tributary) would probably fail for most people anyway (unless their system is set up to build it) :)
