This visualization displays all CSS named colors as equal-sized slices of a circular pie chart, using each color’s RGB hex value to fill its corresponding arc. The chart fills the entire frame because the pie radius is set to the SVG width. The example loads its data from a remote CSV file using D3’s `csv` utility, then uses React’s `useState` and `useEffect` to fetch and store that data. Rendering combines React components with D3’s `pie` and `arc` functions to generate SVG path elements.
