Detailed explanation-1: -Pie charts represent data as part of 100 (a percentage). Each slice represents a different piece of data.

Detailed explanation-2: -Categorical or nominal data: appropriate for pie charts Pie charts make sense to show a parts-to-whole relationship for categorical or nominal data. The slices in the pie typically represent percentages of the total. With categorical data, the sample is often divided into groups and the responses have a defined order.

Detailed explanation-3: -A pie chart, sometimes called a circle chart, is a way of summarizing a set of nominal data or displaying the different values of a given variable (e.g. percentage distribution). This type of chart is a circle divided into a series of segments. Each segment represents a particular category.

Detailed explanation-4: -The most common types of figures used in biology are plots (sometimes called ‘graphs’) which take many forms such as scatter plots and bar charts. However, biological illustrations, maps, and diagrams are also considered figures and must be formatted in the same way. Avoid pie charts at all costs.
