Detailed explanation-1: -A pie chart is a pictorial representation of the data in which the whole is represented by a circle and the parts, by non-intersecting adjacent sectors. Hence, comparison of parts of a whole may be done by a pie chart.

Detailed explanation-2: -Pie charts They use segments of a circle to show the relationship of parts to the whole.

Detailed explanation-3: -A pie chart (or a circle chart) is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice (and consequently its central angle and area) is proportional to the quantity it represents.

Detailed explanation-4: -Clustered column chart Compares values across categories. A clustered column chart displays values in 2-D vertical rectangles. A clustered column in a 3-D chart displays the data by using a 3-D perspective.

Detailed explanation-5: -Use a bar or column chart to compare independent values. We, as readers, are particularly good at comparing the length of bars in a bar chart (in contrast to the segments of a pie chart, for example), making bar and column charts the best charts for showing comparisons.
