Part I. How Do You Create a Pie Chart?
Imagine you have data about the sales distribution of different products. A pie chart can help you showcase the proportions effectively. Here's how you can create a pie chart with percentages on paper.
1. Gather data
Start by collecting relevant data about the categories you want to display in the pie chart. For instance, if you're analyzing sales figures for different products, compile the sales data for each item.
2. Calculate percentages
Calculate the portion of overall sales that each product makes up. Divide the sales of each product by the total sales and multiply by 100. For instance, if Product A generates $10,000 out of $50,000 in total sales, the percentage would be ($10,000 / $50,000) * 100 = 20%.
3. Determine the angle
Pie chart slices represent a percentage. Calculate the angle for each slice by multiplying the percentage by 3.6. If Product A's percentage is 20%, the slice angle would be 20 * 3.6 = 72 degrees.
4. Draw the pie chart
Draw the circle on a piece of paper and divide it into slices according to the angles you calculated. The pie chart slice for Product A would be 72 degrees.
5. Label the chart
Label each slice with the name of the corresponding product. It helps your audience understand which part of the whole each pie chart slice represents, making your data presentation clear.
But, going through all these steps for creating a pie chart, such as calculating angles, can be time-consuming and prone to errors. It is where using a pie graph maker comes in. Such tools can help you create a pie chart saving you time and ensuring accuracy in your data representation.

Part III. When To Use a Pie Chart in Data Visualization?
Now you're familiar with using a pie graph maker. In this section, you'll learn when to use pie charts to present business data.
Situations Where Using a Pie Chart Can Be Appropriate
Here are some scenarios when it's advisable to use a pie chart:
Limited Number of Categories
Pie charts work well when you have a small number of categories to represent. The simplicity of the pie chart helps display the distribution of data without overwhelming the viewer.
Proportional Data Representation
When you need to showcase how different parts contribute to a whole, a pie chart effectively displays the proportions and relative sizes of the categories.
Pie charts are intuitive for displaying percentages. They provide an easy-to-understand visual representation of how much each category contributes to the total.
When You Should be Cautious about Using a Pie Chart
Here are some scenarios when it's advisable to exercise caution when using a pie chart:
Comparing Many Categories
Pie charts become less effective when you have many categories to compare. Smaller differences in slice sizes can be challenging to distinguish accurately.
Pie charts do not convey ordinal information well. For example, a bar chart might better show rankings in your data.
Pie charts are not designed to handle negative values, as they represent parts of a whole.
Showing Trends over Time or Data Groups
Pie charts are not optimal for displaying trends or making detailed comparisons. For instance, you want to showcase the revenue growth of your business over the past five years. A line graph can more accurately capture the upward or downward trends over time.
Complex Data Relationships
If your data involves complex relationships or interdependencies, pie charts might oversimplify the information, potentially leading to misinterpretation.
Part IV. Tips for Pie Chart Data Interpretation and Visualization
Pie graph makers are valuable tools for users to create and visualize data. These tips will guide you to interpret pie charts and make informed decisions.
Begin by identifying and labeling each category. This step lays the foundation for accurate interpretation. Ensure labels are concise yet descriptive, reflecting the data they represent.
Slice Size Significance
The size of each slice correlates with the proportion of data it represents. Larger pie chart slices show a more significant share. Assess these proportions to understand data distribution at a glance.
Color Coding Deliberation
Colors enhance visual appeal and aid differentiation in a pie chart. Select a color palette that remains consistent with your brand or presentation theme. A pie graph maker with a selection of palettes or color themes will be helpful for this.
Limit Slice Count
Overcrowded pie charts can confuse rather than clarify. Aim for a reasonable number of slices (usually 6-8) to avoid overwhelming stakeholders.
Exploded Slices for Emphasis
Consider pulling it out slightly from the center when a specific category requires emphasis. It draws attention to the segment, making it easier for stakeholders to understand its importance.
Data Labels and Percentages
Include data labels and percentage values on each slice. It adds precision to interpretation, allowing stakeholders to grasp the share of each category. Choosing a pie graph maker that lets you change data labels in one click is helpful.
If using a legend, ensure it's clear and close to the chart. It should directly link categories to their labels, avoiding confusion about which color represents which category.
Craft a narrative around your pie chart to guide stakeholders through the data. Explain the key takeaways, trends, and insights, ensuring that even those less familiar with data analysis can grasp it.
Using a pie graph maker online is better than drawing a pie chart on paper. It's convenient, easier, and lets you create professional-looking pie charts that impress everyone.
