Sometimes the graph under consideration might be too dense, with the nodes placed very near to each other. Such a graph makes it difficult to visualize the network, thereby hampering its interpretation and understanding. This is where the Expansion layout algorithm comes to the rescue. Using this algorithm, one can scale up the network and make it appear sparser.
Considering the Les Misérables network, the steps to use the Expansion layout algorithm to get an expanded version of the network are as follows. The steps remain the same for any other network, too:
