With more data points, you will have more slices, and some of them would be very small, making the graph difficult to read/interpret. A pie chart can be easily interpreted if data points are less (around 7). The larger the contribution of an attribute, the larger will be the size of the slice of the pie chart. The company has 5 different attributes, and therefore the pie chart shows 5 divisions (also known as slices of a Pie). For instance, in the above example, we have created a pie chart to represent the expenditure list of an xyz company. Pie charts usually represent the data where the values can be added together or with only one data series (all the data points are positive). The Pie (or the circle) represents the total value, i.e., 100 percent, and each slice of the pie chart adds some per cent to the total. What are Pie Charts? A pie chart is defined as a circular chart with multiple divisions where each division shows the contribution of each value to the total value. They might seem easy, but there are a lot more things you should know about them to represent your data in a detailed and professional manner that can add value for the reader/clients/management.
Pie charts are one of the common elements that are used a lot in Excel worksheets to represent official data.
