This pie chart visualizes the market share of operating systems, showing vehiclesseized values per state as proportional slice labels in thousands (e.g., “123K”). The SVG chart uses D3 v5’s `pie`, `arc` for sector geometry, and `scaleOrdinal` for color mapping, with a legend listing states. Slices are labeled via `arcGenerator.centroid`, while data loads asynchronously from a GitHub-hosted CSV using `d3.csv`. Styling includes a gradient background and customized text fills via CSS.
