This color wheel visualizes all CSS named colors as a single burst of pie slices radiating from the center. Each slice represents one color from the CSS color data loaded via `d3.csv`. The React app uses `useState` and `useEffect` to fetch the data, then renders SVG paths computed with `d3.pie` and `d3.arc`. The `fill` property of each path is set to the color’s hex value from the dataset, creating a full-spectrum circular arrangement.
