This pie chart visualizes the distribution of car horsepower across different makes, using D3 v7 to render SVG arcs and labels. The chart encodes horsepower values as arc sizes and colors each segment by car make, with a legend positioned to the right. Labels are placed along the arcs using `d3.arc`’s centroid method, and the data comes from an inline array of `{make, horsepower}` objects. A hover effect on the paths provides subtle interactive feedback.
