This example renders a radial burst of every CSS named color from a CSV dataset loaded with D3’s `csv` utility. The visualization shows a complete pie chart where each slice’s fill matches its corresponding hex value, using React state and `useEffect` to fetch the data. D3’s `pie()` and `arc()` functions compute the slice geometry, while React’s `map` method generates the SVG `path` elements. The code relies on React 17, ReactDOM, and D3 v7, all rendered as SVG in a 960×500 viewport.
