Pie Chart

A pie chart is a circular statistical diagram that visually represents proportions or percentages of a whole by dividing the circle into slices. Each slice corresponds to a category and is proportional in size to its numerical value.

  1. Circular Shape – The entire chart represents 100% of the data.
  2. Proportional Slices – Each category is displayed as a sector, where the angle of the slice corresponds to its proportion.
  3. Uses Percentages or Absolute Values – Data is typically labeled with percentages or actual values.
  4. Color Differentiation – Each category is usually represented by a distinct color for clarity.
