There are two standard types of serialized graph representations: adjacency list and edge list. The adjacency list is the standard Faunus format - a vertex and all of its incident edges. An edge list, on the other hand, is simply a list of all the edges. The edge list format does not support element properties. The format is outVertexId\tinVertexId\tedgeLabel\n.

The Graph of the Gods data set, when represented as an edge list, looks as as follows.
