This pie chart displays the distribution of horsepower across various car manufacturers. The visualization uses a D3.js pie chart to represent each model's contribution to total horsepower, with percentage labels displayed directly on the slices. A legend maps colors to car models, while the chart includes axis labels for context. The implementation uses d3.pie for slice calculation, d3.arc for path generation, and d3.scaleOrdinal with d3.schemeCategory10 for color assignment. Data is loaded from a remote CSV file and rendered as SVG within a web page.
