Why don't you create an array of contains nodes. So you can check if there is a duplicate — aprogrammer, Dec 01 '16 at 12:06

You can use

graph.getNode(id)

with graph being your VivaGraph instance, which would return null if no node with the given id exists. It is automatically called by graph.addNode(id, data), so it is not possible to create two nodes with the same id anyway.
