Know When Pie, Donut, or Bar Charts Work Best
CHOOSE THE RIGHT CHART
What is a Pie chart?
A Pie chart divides one total into labeled slices, so it is best for a few meaningful shares.
Pie vs Donut
Both show shares. A Donut leaves a center space that can make surrounding labels feel lighter.
Pie vs Bar Chart: When Not to Use a Pie Chart
Use a bar chart when you have many categories or readers need to compare close values precisely.

Frequently asked questions
How do I make a pie chart with percentages online?
Paste one Label, value pair per line into Pie Chart Maker. The preview calculates each category’s percentage automatically. Review the labels, switch between Pie and Donut if needed, and download the finished chart as an editable SVG for a report, worksheet, or presentation.
Do pie chart values need to add up to 100, and how are percentages rounded?
Pie chart values do not need to add up to 100. Enter raw positive numbers such as counts, revenue, visits, or units. Pie Chart Maker calculates geometry from the original values, then uses largest-remainder rounding for whole-number labels so the displayed percentages still add up to exactly 100%.
How many slices should a pie chart have, and when should I use a bar chart?
Use roughly 2–6 slices when each category represents a meaningful part of one total. Too many narrow slices make labels and close values difficult to compare. If the dataset has many categories or small differences, a sorted Bar Chart is usually the clearer choice.
What is the difference between a Pie and Donut chart?
Pie and Donut charts encode the same part-to-whole relationship. A Pie chart fills the center, while a Donut chart leaves it open and can feel lighter in dashboards or presentations. Switch between them without changing the source values, labels, percentages, or legend.
Can I create a Pie chart from Excel or CSV data?
Copy the two required columns from Excel, CSV, Google Sheets, or another spreadsheet, then paste them as one Label, value pair per line. Pie Chart Maker reads the final comma as the value separator, so category labels may contain commas before the final numeric value.
Can I edit the downloaded Pie chart?
Download the Pie chart as SVG to preserve vector paths, text, colors, and labels. Compatible design and presentation software can resize or restyle the SVG without the blur caused by enlarging a bitmap. Always review the exported labels and percentages against the source rows before publishing.
Does Pie Chart Maker require sign-up?
Pie Chart Maker does not require an account for this browser-based Pie and Donut workflow. Open the page, paste the source rows, review the automatic percentages, and download the editable SVG. There is no registration step between entering data and saving the chart.
Is my chart data private?
Pie Chart Maker parses, calculates, and renders the label-and-value rows locally in your browser. The deterministic chart workflow does not send the table to an image-generation model. Avoid placing confidential information in labels, and follow your organization’s data-handling policy when preparing any public chart.
