Have you ever tried to decipher a complex pie chart? If you have, you’ll know first-hand how frustrating it can be if the pie chart is not constructed correctly. Learning to create a pie chart that is informative and easy to interpret can be a game changer for anyone in the field of business, economics, research, or education. In this article, we delve into the world of pie charts and provide steps and tips to create an intuitive and easy-to-read one.
Understanding the Purpose of Pie Charts

Pie charts serve a useful purpose when it comes to presenting statistical data. They provide a quick overview of the distribution of a particular variable. Without even reading the numbers, one can glance at a pie chart and grasp the relative size of different categories.
The concept of a pie chart is simple: it is a circular visualization of data where the whole represents 100% or the total of the data, and the slices represent portions of this whole. This type of chart is particularly useful when you want to show how categories are distributed within a whole.
To choose a pie chart for your data visualization, first consider if the data you want to represent is proportional. It is crucial since pie charts are best suited for displaying data that can be broken down into mutually exclusive categories, each represented by a different slice of the pie.
Essential Elements of an Easy-To-Read Pie Chart
The most crucial element in a pie chart is the use of distinct, contrasting colors. Using colors that are too similar or hues that do not contrast sufficiently can lead to confusion and difficulty interpreting the chart. The use of a legend or key is also important for pie charts, as this will allow the viewer to associate specific colors with categories easily.
Another essential element is the label of the slices. Tiny or overly fancy fonts can be difficult to read, which defeats the purpose of an easy-to-read pie chart. Make sure that labels are concise, clear, and easy to read.
To add clarity, always include percentages for each slice next to the category labels. Including raw data can seem overwhelming and confuse readers, so it’s better to convert the data into percentages which makes it easier to understand at a glance.
Step-by-Step Guide To Creating a Pie Chart
Creating an easy-to-read pie chart is pretty straightforward. You start by categorizing your data into a manageable number of categories. As a rule, the fewer categories, the better, because high segmentation can create confusion.
Next, calculate the percentage of each category. After that, draw a circle and divide it into slices equivalent to the percentage values of each category.
Color the slices differently and clearly to represent each category. Don’t forget to add a legend explaining what each color stands for.
Add labels with their respective percentage values. Remember to take into consideration font size, style, and legibility when doing this. And with that, you’ve created an easy-to-read pie chart
Common Mistakes To Avoid When Creating a Pie Chart

One of the most common mistakes is using a pie chart for data not suitable for this kind of visualization. Remember, pie charts are for showing the distribution of categories within a whole. Other types of data might be better represented by different kinds of charts.
Altogether, when executed right, pie charts can be a powerful tool for conveying complex data simply and understandably. By avoiding common pitfalls and following the suggested guidelines, anyone can create an intuitive and easy-to-read pie chart.
