WebA graph is a mathematical structure that is used to model (pairwise) relationships between objects. In that sense it is an abstract thing and we draw pictures of graphs (for example, the one at left). Graphs are composed of vertices (or nodes/points) and the edges (or arcs/lines) that connect them. Graphs may be connected (when it is possible ... iotop actual vs totalThe small-world phenomena is best known as the six degree of separation, i.e. two persons are related to each other by at most 6 steps in a network of human relationship.
