Pie Charts
Display proportional data distributions with circular charts. Ideal for showing percentages and market share breakdowns.
What is Pie Charts?
Pie charts are circular statistical graphics divided into slices to illustrate numerical proportions. Each slice represents a category's contribution to the whole, with the arc length proportional to the quantity it represents. Pie charts are one of the most recognizable chart types, ideal for showing percentage distributions, market shares, and simple data compositions at a glance.

Common Use Cases
Budget Allocation
Visualize how budgets are distributed across departments, projects, or categories. Make spending patterns immediately visible to stakeholders.
Market Share Analysis
Display competitive landscape with market share percentages. Compare product or company positions in a market at a glance.
Survey Results
Present survey response distributions in an intuitive visual format. Show how respondents are divided across different answer choices.
Resource Distribution
Illustrate how resources like time, staff, or computing power are allocated across different tasks or teams.
Key Features
Automatic Proportions
Simply provide values and Mermaid calculates the correct proportions and angles for each slice automatically.
Chart Titles
Add descriptive titles to provide context for the data being visualized.
Category Labels
Each slice is labeled with its category name and value for clear data identification.
Color Coding
Slices are automatically color-coded with distinct colors for easy differentiation between categories.
Best Practices
Limit Categories
Use 5-7 categories maximum. Too many slices make pie charts hard to read. Group small categories into 'Other'.
Use for Parts of a Whole
Pie charts work best when showing how parts make up a total. Don't use them for comparing unrelated values.
Order Slices Logically
Arrange slices from largest to smallest, or in a meaningful sequence that helps readers understand the data.
Include Values
Always show the actual numbers or percentages alongside slices so readers can make precise comparisons.
