## 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.

### graph

#### Noun

- 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.
- 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>.
- 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

- To draw a graph.
- To draw a graph of a function.
