The undirected graph is also referred to as the bidirectional. It is a set of objects (also called vertices or nodes), which are connected together. Here the edges will be bidirectional. The two nodes are connected with a line, and this line is known as an edge. The undirected graph will be represented as G = (N, E). felidae gattung
