GRAPH

Graph

In mathematics, and more specifically in graph theory, a graph is a representation of a set of objects where some pairs of objects are connected by links. The interconnected objects are represented by mathematical abstractions called vertices, and the links that connect some pairs of vertices are called edges. Typically, a graph is depicted in diagrammatic form as a set of dots for the vertices, joined by lines or curves for the edges. Graphs are one of the objects of study in discrete mathematics.

Noun

  1. A diagram displaying data; in particular one showing the relationship between two or more quantities, measurements or indicative numbers that may or may not have a specific mathematical formula relating them to each other.
  2. A diagram displaying data, in particular one showing the relationship between two or more variables; specifically, for a function <math>f(x_1, x_2, \ldots, x_n)</math>, the set of all tuples <math>(x_1, x_2, \ldots, x_n, f(x_1, x_2, \ldots, x_n))</math>.
  3. An ordered pair <math>(V,E)</math>, where <math>V</math> is a set of elements called vertices (or nodes) and <math>E</math> is a set of pairs of elements of <math>V</math>, called edges; informally, a set of vertices together with a set edges that join these vertices.

Verb

  1. To draw a graph.
