# 3 Types of Graphs

Introduction of graph:

A graph is a chart or drawing that demonstrates the relationship among alternating objects. They are a diagram showing the relationship among numerical values or amounts. The mainly used graphs are bar graph, line graph, and circle graph. Graph that shows the data in a diagrammatic representation. So that it is very interesting for the learner for view and study.

## 3 Types of Graphs:

Let we see about three types graph with this example.

• bar graph
• line graph
• circle graph

These types are explained one by one.

## Line Graph:

This types of graph is extremely used for demonstrating data or information that altered frequently more time. Line graph is also said to be line chart.

Example:

Let us take the population ratio. Population ratio is calculated for every ten years once. The table given below gives the analysis of the population ratio for 6 years, which is shown below. Draw the line graph for the table given below.

Solution:

Explanation:

• The above diagram shows the line graph. From this the year is denoted in horizontal axis and the population in % is denoted vertical axis.
• The interval for x-axis is 10 year and the population percentage interval is 5.
• Now, show the table that is for the year 1950 the corresponding percentage 62 is pointed as a dot in a graph it is placed among 60 and 65.
• Until points all the table values the above step is repeated.
• Now connect all the marked points by a line this gives the line graph.

## Bar Graph:

This type of graph is one of the graph type which effectively shows outcomes that are one time, that aren't continuous - specifically samplings for instance surveys, inventories, and etc,. A bar graph is obviously off with a series of lines called as grid lines. These lines typically mark off a numerical peak in the series of values on the axis or line.

Example:

Let us take one table values that is marks of 5 students, draw the bar graph for this data values.

Solution:

Explanation:

• The above diagram shows the bar graph in which student name is denoted in x axis and the mark is denoted in y axis.
• Now show the table, at first the name honey and the corresponding mark is drawn as a vertical bar.
• This process is repeated until all the datas are plotted.

## Circle Graph:

If the circle is splitted into number of parts or segment then the graph is called circle graph. In this type of graph each part denotes the part of data.

Example:

Let us consider the example for who like the particular fruits which is shown in the below table as a percentage. Now draw the circle graph for these datas.

Solution:
