This visualization displays the CSS named colors as a donut chart, with each color represented by a wedge whose fill matches the color it encodes. The data comes from a CSV file listing named colors and their hex values, loaded asynchronously via `d3.csv`. React manages the component state and rendering lifecycle, while D3’s `pie` and `arc` functions compute the angular layout and path geometry. The SVG output is generated declaratively in JSX, with React re-rendering once the CSV data arrives.
