I have a Family Tree application that uses Django and I am trying to use http://js.cytoscape.org for the UI.
I would like to style edges between romantic partners like this:

which is what you commonly see (the square-U).
I am completely new to Cytoscape.js, and haven't been able to find any answers in the docs or other threads.
