Detailed explanation-1: -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.

Detailed explanation-2: -Pie Chart A pie chart shows a static number and how categories represent part of a whole-the composition of something. A pie chart represents numbers in percentages, and the total sum of all segments needs to equal 100%.

Detailed explanation-3: -Is a pie chart always in percentage? Yes, though sometimes it’s in a roundabout way. While most pie charts list percentages, it’s also possible to create a pie chart using non-percentage data, so long as the data constitutes all parts of the whole.

Detailed explanation-4: -Reading Pie Charts To calculate the percentage each slice is worth, measure the angle of each slice and divide this by 360 then multiply it by 100 . To find the number of pieces of data each slice represents, multiply the percentage that each slice is worth by the total number of the data sets.

Detailed explanation-5: -A pie chart helps organize and show data as a percentage of a whole. True to the name, this kind of visualization uses a circle to represent the whole, and slices of that circle, or “pie”, to represent the specific categories that compose the whole.
