Function of A Graph ...

What is the meaning of Graph? How much of our knowledge on graph application? We know that nowadays,there are many types of graph that has been used .. The functions are same,but the way it being represent maybe in different ways .. So,in this time,we will discuss a little bit about graph function and the best ways to be doing something to the graph .. Take a look ..

A graph is an image that represent data symbolically .. A graph is used to present comlpex information and numerical data in a simple , compact formats .. Bar graphs , line graphs , scatter graphs , and pictographs are some types of graphs ..

In mathematics , a graph is an abstract representation of a set of objects where some pairs of the objects are connected by links. The interconnected objects are represented by mathematical abstraction 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.

The edges may be directed ( assymmetric ) or undirected ( symmetric ) .. In the common sense of the term,a graph is an ordered pair G = ( V , E ) comprising a set V of vertices together with a set E of edges,which are two elements subsets of V (i.e,an edge is related with two vertices,and the relation is represented as unordered pair of the vertices with respect to the particular edge). To avoid ambiguity,this type of graph may be described precisely as undirected and simple. Other senses of graph stem from different conceptions of the edge set. In one more generalized notion. E is a set together with a relation of incidence that associates with each edge two vertices. Many authors call this type of object a multigraph ..
