"WebbEdge lists. One simple way to represent a graph is just a list, or array, of E ∣E ∣ edges, which we call an edge list. To represent an edge, we just have an array of two vertex numbers, or an array of objects containing the vertex numbers of the vertices that the edges are incident on. If edges have weights, add either a third element to ... " - Simple weighted graph
