Graph theory | Data structures In graph theory, a tree is a graph in which any two points, or vertices, are connected by exactly one path (i.e. there are no cycles). A forest is a graph in which any two vertices are connected by at most one path. An equivalent definition is that a forest is graph of one or more (unconnected) trees (hence the name). Trees are useful abstract structural representations of many different concepts.
