This pie chart visualizes the distribution of car models by manufacturer, using a dataset of 50 vehicles with each make occupying one slice of equal size. The chart is rendered with SVG through D3.js, using the `pie` and `arc` generators to compute and draw the segments, while `scaleOrdinal` with `schemeCategory10` assigns colors to each manufacturer. A legend on the right side maps the color-coded slices to their corresponding car brands, and the visualization adapts to the full browser window dimensions.
