This visualization shows the distribution of car classes in a dataset, displaying the proportion of each category as a donut chart with percentage labels on each slice. The chart uses D3.js version 7.8.5, loaded via CDN, to create the pie layout and arc generators, with a categorical color scale mapping four classes—unacc, acc, vgood, and good—to distinct colors. Data is loaded remotely from a CSV file hosted on GitHub Gist, and a legend on the right side displays each class with its raw count. The SVG rendering includes white strokes between slices to visually separate the segments.
