This visualization displays all CSS named colors as a full-circle pie chart, with each color occupying a wedge based on its position in the dataset. The example integrates React and D3, using React’s `useState` and `useEffect` hooks to load CSV data asynchronously, then rendering SVG paths via the `d3.pie` and `d3.arc` utilities. Each wedge is filled with its corresponding hex value from the CSS named colors dataset, which is fetched from a gist URL.
