This visualization displays the full list of CSS named colors as wedges in a semi-circular pie chart. It loads color data from a CSV file using `d3.csv`, then renders each color as an SVG path generated with `d3.arc`. React manages the data-fetching state via `useState` and `useEffect`, while `ReactDOM` renders the SVG structure. The chart uses a fixed arc with an inner radius of zero and an outer radius matching the viewport width.
