"WebGraph Data Structures The primary property of a graph to consider when deciding which data structure to use is sparsity , the number of edges relative to the number of vertices in the graph. A graph where E is close to V 2 is a dense graph, whereas a graph where E = alpha V and alpha is much smaller than V is a sparse graph. " - Graph database theory
