A React application renders a color wheel from CSS named colors loaded as CSV data from a GitHub gist. The program uses React hooks (`useState`, `useEffect`) to fetch and parse the data with `d3.csv`, then maps each color to an SVG path segment using `d3.arc`. With dimensions of 960 by 500, each path is positioned around a central point, its fill set to the color’s hex value, creating a full circular visualization of all named colors. The D3 arc generator defines each segment’s angle based on the data index.
