This pie chart displays the income of the top 10 Indian states for the financial year 2011–12, with each slice colored via d3.scaleOrdinal and d3.schemeCategory10. The data is loaded from a CSV using d3.csv, sorted, and sliced before being rendered with d3.pie and d3.arc. A custom legend, built with SVG rectangles and text, shows each state’s name and income value alongside its color. Mouseover events log the corresponding income value to the console.
