This pie chart visualizes the number of car units sold for different car models, with each slice colored distinctly and accompanied by a legend showing the car name and its corresponding value. The chart uses D3 v5’s `pie`, `arc`, and `scaleOrdinal` functions to generate the SVG paths, while data is loaded asynchronously from a CSV file via `d3.csv`. The rendering includes a centered pie with a 200-pixel outer radius, and the legend displays colored rectangles and text labels positioned to the right.
