Are you looking for a way to make your data more visually appealing? If so, then you should learn how to create a pie chart. Keep reading to learn more about this data visualization tool.
What is a pie chart?
A pie chart (or “pie diagram”) is a graphical representation of data, in which a pie-shaped wedge is drawn for each proportion of the whole. In a pie chart, the arc length of each wedge is proportional to the quantity it represents. The total arc length is equal to the sum of the arc lengths of all the wedges. For example, in a pie chart demonstrating how a company’s revenue is divided among its products, the arc length of each wedge would be proportional to the revenue generated by that product.
Pie charts can be used to compare two or more different quantities. For example, in a pie chart comparing the number of men and women in a company, the arc length of the wedge for men would be proportional to the number of men in the company, and the arc length of the wedge for women would be proportional to the number of women in the company.
Pie charts can also be used to compare proportions at different points in time. For example, in a pie chart comparing the number of men and women in a company at two different points in time, the arc length of the wedge for men at the first point in time would be proportional to the number of men in the company at that point in time, and the arc length of the wedge for women at the first point in time would be proportional to the number of women in the company at that point in time.
How do you create a pie chart?
To create a pie chart in Excel, you need to have at least one data series. The data in the data series must be in percentages.
To create a pie chart:

11. To move the chart, under Chart Elements, click the arrow next to Location and then click the location that you want.
How do you interpret a pie chart?
There are some general tips that can help you read any pie chart effectively: Start by identifying the total size of the pie chart. This will give you a sense of the overall magnitude of the data. Next, look at the percentages represented by each slice of the pie. This will give you a sense of how the data is distributed. Finally, focus on the individual slices to get a more detailed understanding of the data. Try to identify any patterns or trends that may be present.
Overall, pie charts are a great data visualization tool!
