The test case has one using a python shell to test the import of
networkx yet the verification comment does not do this. Please verify
the bug following the test case.

Title:
  [SRU] Bionic missing dependency for pydotplus

Status in python-networkx package in Ubuntu:
  Invalid
Status in python-networkx source package in Bionic:
  Incomplete
Status in python-networkx source package in Cosmic:
  Invalid
Status in python-networkx source package in Disco:
  Invalid

Bug description:
  [Impact]
  python-networkx in bionic is missing a dependency on python(3)-pydotplus. The versions in cosmic and disco no longer use pydotplus. The fix would be to add python(3)-pydotplus to Suggests in bionic since it is not in main.
