This visualization displays vehicle registration counts as a donut pie chart, with each slice labeled by its value in thousands and color-coded by vehicle type. A legend on the right lists each type alongside its corresponding count. Built with D3 v5, the code uses `pie` and `arc` to generate the slices, `scaleOrdinal` for colors, and `csv` to load the dataset from a GitHub gist. The SVG output is rendered through `select` and appended paths and text elements.
