`%%opencypher` should render detailed nodes if returned edges contain sufficient information

[michaelnchin]

Is your feature request related to a problem? Please describe.

When %%opencypher retrieves a result set containing only relationships, the IN/OUT vertices for these relationships are always rendered as blank nodes, unlabeled and with the default group color.

Example %%oc visualization:

For comparison, the %%gremlin visualizer already behaves in the intended manner described when given only edges containing sufficient node information (i.e. via elementMap):

Describe the solution you'd like

When relationships returned via %%opencypher contain sufficient information (ex. ~id) about the connected nodes, this information should be used to customize the appearance of the visualized nodes, instead of rendering them blank.
