Pie charts are a popular way to show how different categories contribute to a whole. Each segment represents a proportion of the total, making it easy to see which groups are largest or smallest at a glance. However, pie charts are not always the best choice for every dataset. When segments are similar in size, it becomes difficult to compare them accurately. Too many categories can also clutter the chart, reducing clarity and making it hard to interpret.

For effective use:

  • Keep the number of segments low—ideally five or fewer;
  • Use clear, contrasting colors for each slice;
  • Always label segments or provide a legend so viewers can quickly understand what each part represents.

Consider alternative chart types, like bar charts, for more precise comparisons between categories.
