This visualization displays all CSS named colors as equal-sized slices in a circular arc chart rendered as an SVG. The data is loaded from a CSV file using D3’s `csv` utility, and each color’s hex value fills its corresponding arc segment. The chart is built with React’s `useState` and `useEffect` hooks to manage the fetched data, while D3’s `arc` and `pie` functions compute the arc paths. A loading placeholder appears until the data arrives.
