This pie chart displays the top 10 billionaires and their net worth in billions of dollars, sourced from the DailyDelhiClimateTest.csv dataset. It uses d3.pie and d3.arc to generate SVG segments, with d3.scaleOrdinal assigning colors from a custom palette. Each segment includes value labels positioned via arc.centroid, and a legend lists names with corresponding values. The chart renders in SVG with a gradient background, leveraging d3.csv for data loading and d3.format for tick number formatting.
