Pie chart is perhaps the most common method to represent data quantitatively. It shows how much of a certain category contributes to the overall population. It is also used to compare one value set from another, but only if the values are too large or too small. Close values are compared best by a bar graph. A pie chart comprises of slices, each of which represents a given value in the form of numbers, percentages, series’ names and other forms.  From advanced chart labeling to simple worksheet tab options, Excel lets users create wholly customizable pie charts from myriad design options.  The experience is both creative and professional.
