This example displays every CSS named color as a single path filling a semicircular fan, with each color’s RGB hex value used as the fill. The visualization uses React’s `useState` and `useEffect` to fetch the CSV data, then maps each row to an SVG `<path>` generated by the D3 `arc()` generator. The chart renders via React’s virtual DOM, while D3.js v5 handles the data loading and geometry calculation, producing a static, non-interactive radial color catalog.
