A pie chart (or a circle graph) is a circular chart divided into sectors, illustrating proportion. In a pie chart, the arc length of each sector (and consequently its central angle and area), is proportional to the quantity it represents. When angles are measured with 1 turn as unit then a number of percent is identified with the same number of centiturns. Together, the sectors create a full disk. It is named for its resemblance to a pie which has been sliced. The earliest known pie chart is generally credited to William Playfair's Statistical Breviary of 1801.[1][2]
The pie chart is perhaps the most widely used statistical chart in the business world and the mass media.[3] However, it has been criticized,[4] and some recommend avoiding it,[5][6][7][8] pointing out in particular that it is difficult to compare different sections of a given pie chart, or to compare data across different pie charts. Pie charts can be an effective way of displaying information in some cases, in particular if the intent is to compare the size of a slice with the whole pie, rather than comparing the slices among them.[1] Pie charts work particularly well when the slices represent 25 to 50% of the data,[9] but in general, other plots such as the bar chart or the dot plot, or non-graphical methods such as tables, may be more adapted for representing certain information. It also shows the frequency within certain groups of information.

What is the definition of interpreting of pie charts?
Sometimes, information is presented in the form of a pie chart because that is an easy way to visualize fractions. Most of us have, at some point in our lives, had to share a pie with some other person or people. We therefore have a concrete understanding of what it means to divide a pie into three sections. So metaphorically, we can visualize anything as a pie. We might use a pie chart to show how your tax dollars are spent. This slice is for national defense, this slice is for medicare, this slice is for interest payments on the national debt, and so forth. When we talk about interpreting pie charts, we simply mean looking at a pie chart and understanding what it means. We see that the US is spending quite a lot of its available money on interest payments. We see how big the slice is, of that particular pie. Perhaps this will tell us something about why it is not a good idea to be massively in debt.
