This pie chart shows the distribution of car brand sales for six brands, with each slice sized proportionally to its sales figure and labeled directly on the chart. A color-coded legend to the right identifies each brand. Built with D3 v7, the visualization uses `d3.pie()` to compute the arc angles and `d3.arc()` to render the SVG paths, while `d3.scaleOrdinal` with the `schemeTableau10` palette assigns colors, and labels are placed using the arc centroid method.
