.addGraph

Is there a way to add an entire graph rather than graph.addNode() and graph.addLink() for all items ? I can see this being useful if you have multiple graphs or different instances where not all classes are the same.

Start by locating the graph.addNode() and graph.addLink() entry points and reviewing how graph instances are represented. Determine the intended behavior for adding an entire graph, including graphs with different classes; the work is complete when the API and its expected behavior are defined and covered by tests.
