"""Simple script that tests CytoscapeGraphDrawer.

This script is kept separate from the unit tests as it is very
hard to test for the correctness of CytoscapeGraphDrawer without
a working instance of Cytoscape.

Prerequisites for running this test:

    1. Start Cytoscape
    2. Activate the Cytoscape RPC plugin, listening at port 9000
