A pie chart is a circular diagram divided into slices to illustrate numerical proportion. It is often used to represent parts of a whole, as in showing how much of the total that each thing represents. A pie chart can be used to compare various categories of data, such as age groups and ethnicity, or the time each sales rep worked on a project.
Who Made That Pie Chart? – History of Pie Charts
The earliest known inventor of a pie chart was William Playfair (1759-1823), an economist who is credited with inventing the line graph, bar chart, and box plot. Pie charts are used to illustrate numerical proportion and have existed for over 200 years. One of their earliest uses was in 1801 by William Playfair in his Statistical Breviary to illustrate population.
Pie charts continue to be used for this purpose but are now also commonly used to show other types of data as well.
Where are pie charts used?
Commonly used in presentations and offices, Pie Charts help to show proportions and percentages between categories by dividing a circle into proportional sections. Each arc length represents a proportion of each category, while the full circle represents the sum of all data equal to 100%.
It is possible to give many different examples in this regard.
- It is used to compare voting rates in elections.
- It is used to evaluate the rating rates on televisions.
- It is evaluated for products produced within a certain timetable.
- Evaluates the proportional amount of agricultural products produced in any region.
- It is used to show the production amount of a product over the years.
How does a pie chart differ from other types of charts?
Other types of charts perform better when used to show data in pictorial format. For example, if you want a visual representation of sales performance over time and you have monthly or quarterly sales figures for several years, it makes more sense to use a line chart rather than a pie chart.
In this case, you would use the line chart as a secondary graph and place it below the pie chart. So when do you use a pie chart? The answer is simple, but it needs some thought: first, ask yourself if your data lends itself well to portraying information in pictorial form. If so, then consider using pie charts.
Let’s see other charts.
Bar Chart
This bar chart does a good job of comparing how each category has changed over time. The categories are grouped together in batched elements, so the Chart does not imply the part-whole relationship. This Chart lacks an understanding of who we are comparing the differences to or what other changes have occurred that might have affected those bars.
Donut Chart
A Donut Chart is like a pie chart but with a hole in the middle. The “donut” serves to display another layer of data, revealing the proportions of each item within the whole. You can use donut charts to show comparisons between items that are not exactly comparable.
Ring Chart
Ring charts are useful when you have more than one dimension of data to explore, but it can be difficult to read more than one point on the same ring.

The Pie Chart is a visual tool that is used to display parts of a whole, as in percentages. Each slice of the Pie represents a percentage of the whole. It is often used to represent statistical data on various topics such as sales, earnings, distribution, etc. This makes it an excellent choice for sharing complex data.
