Pie charts are different types of data presentation. This data is presented in the form of a circle. There are segments and sectors into which a pie chart is being divided and each of these segments and sectors forms a certain portion of the total(in terms of percentage). In the pie-chart, the total of all the data is equal to 360 degrees. The degree of angles that are used to represent different items are calculated in the form of proportionality.
Step-by-step explanation:
Pie charts

For, the example you can see the distribution of sales of the laptop industry between five companies:
Company % in market share
HP 22
Dell 33
Lenovo 13
Asus 15
Acer 17
The pie chart represented above shows a circle of 360 degrees which represents 100 % of the values of the continuous variable. Thus, 3.6 degree of the pie chart represents 1 % of the total values of the variables being represented. Pie-charts are more versatile than the bar graphs, tables or two variables graphs. It also represents the clear and precise data that needs to display. Thus, also helps you establish the relationship between different sectors.
