A pie chart displays the proportional quantities of five car models from a CSV file, with slices labeled by name. The static SVG visualization is built using D3 v7, loading data via `d3.csv` and computing arc paths with `d3.arc`. A categorical color scale from `d3.scaleOrdinal` colors each slice, while a custom legend lists the model names alongside colored swatches. The chart is rendered inside an SVG canvas with fixed dimensions, and slice labels are positioned using arc centroids.
