Pronunciation: [pˈa͡ɪ t͡ʃˈɑːt] (IPA) 
The correct spelling for the popular chart that displays data in portions or percentages is pie chart. Pronounced /paɪ tʃɑːrt/, it is spelled with the letters P-I-E followed by C-H-A-R-T. The 'i' in pie is pronounced like the 'i' in the word 'hi', while the 'e' in chart is pronounced like the 'a' in the word 'car'. The word derives its name from its shape, which resembles a sliced pie or pizza.
A pie chart is a graphical representation that displays data using a circular diagram, divided into sections or slices, which represent the relative proportions or percentages of the different categories or components being measured. It is a visual aid commonly used to illustrate the distribution, composition, or comparison of various elements within a whole.
The circular shape of the pie chart represents the total value or entirety of the data, known as the whole or 100%. Each slice within the chart corresponds to a specific category or data point and represents its proportionate share relative to the whole. The size of each slice is determined by the value or percentage it represents, making it possible to visually perceive the relative importance or contribution of each category.
Typically, pie charts are utilized to present data that can be classified into discrete or categorical variables rather than continuous data. They are often employed in fields such as statistics, business, economics, and research to depict information such as market shares, budget allocations, survey results, population distributions, or any other data that can be divided into distinct categories.
Pie charts are visually appealing, easy to interpret, and efficiently communicate a clear snapshot of the data at a glance. They provide an intuitive understanding of proportions and facilitate comparisons between different categories. The colorful or shaded slices, accompanied by a legend or labels, help identify and differentiate each category, aiding in comprehension and analysis. Overall, pie charts serve as a powerful tool for effectively visualizing and communicating data patterns, trends, and relationships.
The word "pie chart" originates from the resemblance of the circular chart to a pie, particularly when it is divided into slices. The term "pie" refers to a dessert consisting of a filling enclosed in a pastry shell. The chart's segmented structure resembles slices of a pie, representing different categories or proportions. The use of pie charts to visually display data became popular in the early 1800s, and the term "pie chart" has been in use since then, describing this specific type of graphic representation.
