Pie charts are circular charts used to show how individual categories contribute to a whole. The most common types of pie charts include standard pie charts, donut charts, 3D pie charts, exploded pie charts, and multi-level pie charts (sunburst diagrams). Each type is suited to different data visualization needs, from business reports and financial analysis to dashboards and survey results.
Key Takeaways
Pie charts remain one of the most popular ways to visualize data because they clearly show how individual categories contribute to a whole. From business presentations and marketing reports to financial dashboards, pie charts help transform complex numbers into easy-to-understand visuals. Modern charting libraries like FusionCharts also make it easy to build interactive pie charts with animations, drill-down capabilities, custom labels, and responsive designs.
In this guide, you’ll learn about the different types of pie charts, when to use each one, their advantages and limitations, and best practices for creating effective visualizations.

Pie chart is the information shown in a circular sectioned chart. It is a graphical representation of data where the pie slices depict the data’s relative sizes. A list of numerical and categorical variables is necessary for a pie chart. Pie, in this context, refers to the entire thing and slices it into its component portions.
The pie chart, commonly referred to as a “circle chart,” divides the circular statistical visual into sectors or portions to show mathematical issues. A proportional amount of the whole is indicated by each section. The Pie-chart is now the most effective method for determining the composition of anything. Pie charts typically take the role of other graphs, such as bar graphs, line plots, histograms, etc.
Although a pie chart cannot precisely represent all percentages, they are utilized to depict them. A pie chart is still mostly used to illustrate percentages or components of a whole.
A pie chart works well to depict data divided into discrete pieces. The use of a pie chart is to compare how much each component of the data contributed to the overall data.
A pie chart is easiest to read when it contains five or fewer slices. Too many categories make individual segments difficult to distinguish, reducing the chart’s effectiveness.
Unlike line charts or area charts, pie charts do not show changes over time. They are designed to represent data from one specific period or snapshot.
Businesses often use pie charts to visualize expenses, departmental budgets, revenue sources, and investment allocations because percentages are easier to interpret visually.
Pie charts come in several variations, each designed for different data visualization needs. The most common categories include:
Donut Chart
A donut chart is a variation of a pie chart with a hollow center. It presents the same proportional data as a standard pie chart while leaving space in the middle to display additional information, such as totals, labels, or key metrics. Donut charts are ideal for:
Compared to a standard pie chart, a donut chart often provides a cleaner appearance while making room for contextual information.
A 3D pie chart adds depth and perspective to a traditional pie chart, making it more visually appealing for presentations. It highlights the relationship between different categories while creating a more engaging visual. Common uses include:
Although 3D pie charts improve visual appeal, excessive perspective can make slice sizes harder to compare accurately. For analytical reports, a standard 2D pie chart is often the better choice.
An exploded pie chart separates one or more slices from the rest of the chart to draw attention to specific categories. This makes it easier to emphasize important values without changing the underlying data. Exploded pie charts are commonly used to highlight:
Use exploded charts sparingly, as separating too many slices can reduce readability.
Both 2D and 3D pie charts display proportions, but they differ in readability and presentation style.
| Feature | 2D Pie Chart | 3D Pie Chart |
| Readability | Excellent | Good |
| Visual Appeal | Simple and clean | More engaging |
| Data Accuracy | Easier to compare slices | Perspective may distort sizes |
| Best For | Reports, dashboards, analytics | Presentations and executive summaries |
A well-designed pie chart makes data easier to understand at a glance. Following a few best practices can improve readability and help your audience interpret the information more accurately.
Pie charts work best with five or fewer categories. Too many slices make the chart cluttered and difficult to read.
Place slices from largest to smallest or follow a natural sequence. This makes it easier for readers to compare values.
Add labels or percentages directly to each slice so users don’t have to estimate values. This improves clarity, especially in business reports.
If several categories contribute only a small percentage, combine them into an “Other” category to simplify the chart.
Use contrasting but consistent colors to distinguish slices. Avoid using too many similar shades, as they can make the chart harder to interpret.
There are many alternatives to pie charts such as bar and waffle charts. Let’s discuss these examples in more detail.
Each chart has its strengths, so choosing the right one depends on your data and presentation goals.
FusionCharts makes creating React Native graphs simple. Without a doubt, the full JavaScript framework for interactive and dynamic charts.

Pie charts are an effective way to visualize proportional data, making it easier to understand survey results, financial reports, and business insights. Choosing the right pie chart type and following visualization best practices ensures your data is clear, accurate, and engaging. With FusionCharts, you can create interactive and customizable pie charts that enhance data visualization across modern web applications.
A donut chart is a variation of a pie chart with a hollow center. While both display proportions, the center of a donut chart can be used to display totals, KPIs, or additional information.
Use a sunburst diagram when your data contains multiple hierarchical levels or nested categories. A standard pie chart is better suited for simple, single-level datasets.
For most business presentations, standard pie charts and donut charts provide the best balance between readability and visual appeal. Exploded pie charts can be used to emphasize important data points.
A waffle chart makes percentages easier to compare, while a pie chart provides a quicker view of parts of a whole. Waffle charts are better for detailed comparisons, whereas pie charts are more familiar and simpler to interpret.
Standard pie charts are best for simple financial breakdowns, donut charts for dashboards and KPIs, and exploded pie charts for highlighting key financial categories.
