A pie chart displays the selling price of Fortuner cars across different years, with each slice representing a year and the price encoded by color. The chart renders as an SVG using D3.js v5, loading data from a CSV file hosted on GitHub Gist. The code uses d3.pie, d3.arc, and d3.scaleOrdinal to generate the chart, with labels positioned via arc.centroid and a legend built from the same data.
