This visualization displays all CSS named colors as a circular pie chart where each color occupies an equal slice. The application loads color data from a CSV file using `d3.csv`, then uses React's `useState` and `useEffect` hooks to manage the asynchronous data fetching and rendering. The chart is constructed with `d3.pie` and `d3.arc`, generating SVG paths filled with each color's corresponding hex value, centered within a 960 by 500 viewport.
