In mathematics, we call a visual representation of a network a graph. A graph is a collection of points, called vertices, and line segments connecting those points, called edges. The number of edges that belong to a vertex is called the degree of the vertex.
For example, a graph is said to be connected if each pair of vertices in the graph is joined by a path. This definition is equivalent to the topological one, as applied to graphs, but it is easier to deal with in the context of graph theory.roperties and parameters based on the idea of connectedness often involve the word connectivity. For example, in graph theory, a connected graph is one from which we must remove at least one vertex to create a disconnected graph. In recognition of this, such graphs are also said to be 1-connected.
