Synopsis
========

The graph subcommand is unable to access files in the share directory.

Analysis
========

/usr/local/lib/python3.7/site-packages/dnsviz/config.py sets

    _prefix = ''

instead of

    _prefix = '/usr/local'

During the package building process, it appears that install_data is only populated with the real prefix during the stage target, by which point a copy of config.py has already been generated with the empty prefix.
