Simple graphs

You can read the basic things in wikipedia. You only need to understand what a graph is, know some basic definitions, and be able to store graphs in a program. Of the ways to store the graph, the adjacency matrix and adjacency lists will be enough for you for now. You don't need graph traversals yet (until the next topic).
