What is a Doughnut Chart?

A doughnut chart is a variation of a pie chart with a hollow center. It represents data in a circular format, where each slice (or segment) corresponds to a portion of the total value. The empty center can be used to display additional information, such as a total value or key insights.

Features of a Doughnut Chart

  • Hollow Center: The most distinctive feature is the empty space in the middle, which can be used for labels or other visual elements.
  • Proportional Representation: Each slice is proportional to its value relative to the whole dataset.
  • Multi-Series Capability: Supports multiple rings to represent different datasets in a single chart.
  • Customizable Appearance: Colors, labels, and slice thickness can be adjusted for better visualization.

Advantages of Doughnut Charts

  • Clear Data Representation: Shows how individual parts contribute to a whole.
  • Enhanced Readability: The hollow center allows for additional information without crowding the chart.
  • Aesthetic Appeal: More modern and visually appealing compared to traditional pie charts.
  • Multiple Data Layers: Supports nested doughnut charts to compare multiple datasets.

Disadvantages of Doughnut Charts

  • Limited Precision: Difficult to compare slices with similar sizes accurately.
  • Clutter with Many Categories: Becomes hard to read if there are too many segments.
  • Interpretation Issues: Less intuitive than bar charts for precise value comparison.

When to Use a Doughnut Chart

  • Categorical Breakdown: Ideal for showing the proportion of categories within a dataset.
  • Summarizing Data: Great for summarizing data while utilizing the center for additional insights.
  • Comparing Multiple Series: Useful when comparing different datasets using multiple concentric rings.
