This example visualizes CSS named colors as a radial burst, with each color represented as a wedge of a pie chart. The code loads color data from a CSV file using D3’s `csv` utility, then uses React hooks (`useState`, `useEffect`) to manage asynchronous data loading and state. D3’s `pie` and `arc` generators compute the wedge geometry, and React renders each slice as an SVG `<path>` filled with the corresponding hex color. The visualization updates when data arrives, showing a full circle of color segments.
