1.	With the help of suitable examples, explain the following: (a) Bar graph. (b) Pie diagram
Answer» Bar graphs are used to display data in a similar way to line graphs. However, rather than using a point on a plane to define a value, a bar graph uses a horizontal or vertical rectangular bar that levels off at the appropriate level. When the information is shown through a circle, it is called a pie chart. Pie charts are often used when it is necessary’ to show the relationship of parts to a whole. If you use too many segments in the pie, the impact could be lost. We represent the information in the pie through’ percentage. In this chart shading may be used to focus special attention on a single element.
