WHAT IS PIE CHART

A pie chart is used to demonstrate a group of data in appearance or other places where the facts of the data set are not essential. Its best utility comes when trying to contrast various data peaks as a percentage of an entire. Because of its restricted capacity, it is seen more in business than technical applications. Most spreadsheet programs contain the capability to create pie charts, but it is simple to do by hand for little sets of data.
