This pie chart visualizes vehicle registration data, displaying the proportional counts of different vehicle types as colored slices. The chart uses orange, pink, yellow, and light blue sections, each labeled with its count and accompanied by a legend that identifies the vehicle type and value. Built with D3 v5, the visualization fetches data from a CSV file using `d3.csv` and constructs the pie chart with `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` for color mapping. The SVG output includes value labels positioned via arc centroids and a separate legend group.
