A pie chart is a type of chart that visually presents the proportion of parts in a whole by dividing a circle into multiple sector areas. In a pie chart, the circle (360°) is divided into multiple sector areas in proportion, with each sector's area size proportional to the corresponding data value, using an intuitive analogy of "cutting a cake" to convey the proportional relationship.

With ProcessOn, there's no need to import external files or manually clean data. Simply drag a pie chart template into the canvas, enter the category name and value in the pie chart data box, and the system will automatically calculate the proportions and generate a basic pie chart.
Additionally, the template community offers a wealth of pie chart examples for your reference and use.
In addition to basic pie charts, ProcessOn also supports creating various other types of pie charts online, including donut charts, 3D pie charts, parent-child pie charts, and Nightingale rose charts. Users can freely combine preset fan-shaped modules, intuitively adjust proportions, and use various color schemes to quickly create pie charts suitable for brainstorming, teaching demonstrations, and other visualization scenarios.
A pie chart with a hollow center, similar to a basic pie chart, also displays the proportion of each part through sector areas. The blank central area can be used to add additional information, such as the overall value, title, icon, etc., enhancing the information transmission capacity of the chart.
A composite pie chart is usually a combination of a main pie chart and a secondary pie chart. The main pie chart shows the main categories and their proportions, while the secondary pie chart further subdivides one or several sectors of the main pie chart.
Also called a polar area chart, it divides the polar coordinate plane into several equal-angle areas and fills the corresponding equal-angle areas based on different data sizes. The stretched length is proportional to the value size of the category, which can better highlight the value differences between different categories.
Use with caution: Only show the proportion relationship of a small number (≤6 categories) in the whole, avoiding multiple categories or precise comparisons.
Simplify categories: Merge minor items into 'Others' to ensure distinguishable sectors.
Highlight sorting: Arrange by proportion from large to small, with key categories at the front or highlighted.
Clear coloring: Use contrasting colors to distinguish sectors, avoiding too many colors.
Clear labels: Directly label percentages and category names, using guide lines if necessary to avoid overlap.
Prefer alternatives: Use bar charts for many categories, line charts for trends.
Verify total: Ensure percentages sum to 100%, with an error ≤1%.
Drag the 'Text' graphic from the 'Basic Graphics' section on the right to above the pie chart, and double-click to set the title.
Double-click the pie chart, and add text or numbers in the dashed box of existing categories or series in the right menu bar.
Double-click the pie chart, select series, category names, or specific data in the right menu bar, click the 'Delete' button, and choose to delete the entire row or column.
Double-click the pie chart, and you can hide the legend in the right menu bar.
In ProcessOn, use the pie chart from the 'Chart' type in flowcharts, and it will automatically display after filling in the data.
Click the 'Download' button at the top right to export the pie chart as PNG, JPG, PDF, etc.
