Do you need to show different views of the same data model? Display only a subset of what the graph actually contains. The paper viewport option can prevent arbitrary models from displaying as we have demonstrated in the demo below.
Manipulate common elements and observe their behavior in both views, or move sub-elements of the graph and observe their movement in only one of the views.
