How it works

Enter your data as comma-separated values with category label and numeric value. Each row becomes a slice of the pie. The tool automatically calculates percentages based on the total.

Customize the chart with a title, donut hole size (0 for pie, higher for donut), and toggle labels and legend. Colors are automatically assigned from a vibrant palette.

Data format:

Category, Value Sales, 35 Marketing, 25 Engineering, 40

The chart renders instantly with interactive tooltips showing exact values and percentages. A data summary table displays all categories with their values and percentage of total.

When You'd Actually Use This

Budget allocation visualization

Show how budget is distributed across departments or categories. Stakeholders instantly see where money goes. Useful for board presentations and annual reports.

Market share comparison

Display company market share vs competitors. Visual impact of being #1 or #2 is immediate. Investors grasp competitive position at a glance.

Survey response breakdown

Show distribution of multiple-choice responses. What percentage chose each option? Pie charts make proportions intuitive for non-technical audiences.

Website traffic sources

Break down traffic by source: organic, paid, social, direct. Marketing teams see channel performance. Helps allocate marketing budget effectively.

Product category sales

Show revenue contribution by product line. Identify which products drive most revenue. Inventory and marketing decisions become data-driven.

Time allocation tracking

Visualize how time is spent across activities. Personal productivity or team capacity planning. Identify where time actually goes vs where you think it goes.

What to Know Before Using

Limit the number of slices.More than 6-7 slices becomes hard to read. Small slices look similar. Group minor categories into "Other" for cleaner charts.

Pie charts show parts of whole.All slices must add to 100%. Don't use for unrelated values. If categories don't form a complete whole, use a bar chart instead.

Humans aren't great at angle comparison.Similar-sized slices are hard to distinguish. Add percentage labels for precision. Consider bar charts for precise comparisons.

Donut charts have the same data.Donut (with hole) vs pie (solid) is aesthetic preference. Donuts can show a total in the center. Both encode data the same way.

Pro tip: Order slices from largest to smallest, starting at 12 o'clock. This creates a natural reading order. Put "Other" last regardless of size.

Common Questions

How many categories work best?

3-5 categories is ideal. 6-7 is acceptable. More than that, consider grouping or using a different chart type. Readability decreases with more slices.

Can I use negative values?

No, pie charts require positive values that sum to a meaningful total. Negative values don't make sense in a parts-of-whole visualization.

Should I show percentages or values?

Show both if space allows. Percentages show proportion, values show magnitude. Labels can display "Category: Value (Percentage)" format.

What if two slices are similar size?

Add percentage labels for clarity. Consider exploding (pulling out) similar slices. Or use a bar chart which makes small differences more visible.

Can I customize the colors?

This tool auto-assigns colors from a palette. For custom colors, download the SVG and edit in a vector tool, or use a more advanced charting library.

When should I use a donut instead of pie?

Donuts look modern and can display a total in the center. Some studies suggest donuts are slightly easier to read. It's mostly aesthetic preference.

How do I export for presentations?

Download as PNG for PowerPoint or Google Slides. For print publications, SVG provides infinite scalability. Both formats preserve chart quality.
