Pie charts represent categorical data as slices of a circle, where each slice’s angle or area corresponds to a category’s proportion. For instance, if a total budget is ₹10,000 and marketing gets ₹2,500, that slice is 25% of the pie or 90° out of 360°. To plot, calculate each category’s percentage, multiply by 360 to get slice angles, and then draw accordingly. Pie charts offer quick visual breakdowns of how parts contribute to a whole, aiding in budget distributions, poll results, and market share analysis. Mastery ensures your data storytelling is intuitive, vivid, and effective.
