This pie chart displays the distribution of horsepower values across different car makes, with each genre category represented as a colored slice proportional to its count. The visualization loads a CSV dataset via Papa Parse, then uses D3 v7’s `pie` and `arc` generators to compute slice paths and centroids, rendering labels at each slice’s center. Slices are filled with a categorical color scheme and separated by white stroke lines, while the SVG canvas is centered within a responsive container.
