A Graph is a diagram showing data, in particular one showing relationships between two or more quantities, measurements or indicative numbers that may or may not have a specific mathematical formula relating them to each other.

It is a pictorial representation that represents data or value in an organized manner.

The points on the graph often represent the relationship between two or more things.

A good example of a graph is a pie chart.
A graph consists of some points and line between them. The lengths of the lines and the position of the point do not matter.

Types of graph

1.Line graph
2.Bar graph
3.Pictograph
4.Histogram
5.Area graph
6.Scatter plot

Graph is a common way to visually illustrates relationships in data.

The purpose of a graph is to present data that are too numerous or complicated to be described adequately in the text and in less space.

Once a data shows or displays relation between variables, a graph should be used.

A circle graph is usually used to easily show the results of an investigation in a proportional manner.

1.Social graph.

2.Recommendation engines.

3.Path optimization algorithms.

4.Scientific computations.

5.Knowledge graphs.

Graphs are very useful tools in science, they can help you visualize a set of data.

Profession and its uses of graph

1.Statisticians.

2.Weather graph.

3.Graphing medical research.

4.Graphing risk.

Software engineers use graphs to represent communication networks, data, organization, computational devices and the flow of computation.

The use of graph theory helps engineers optimize the density of components and minimizes the connections which optimizes processing speed and electrical efficiency.
