Graph theory: A set of nodes (also called points or vertices) connected by links called lines or edges or arcs. In an undirected graph, a line from point A to point B is considered to be the same thing as a line from point B to point A. In a directed graph, the two directions are counted as being distinct arcs or directed edges.
Mathematics: A diagram exhibiting a relationship, often functional, between two or more sets of numbers as a set of points having coordinates determined by the relationship. Also called a plot.
Computer science: A data structure representing relationships or connections in lists, trees, and networks.
Data visualization: Any pictorial device such as a point graph, surface graph, or symbol graph used to display numerical relationships.
