This example shows a radial burst of the CSS named colors, with each color represented as a slice of a pie chart. It uses React hooks like `useState` and `useEffect` to asynchronously load the data with `d3.csv`, then renders SVG paths via React. The `d3.pie` and `d3.arc` APIs compute the angular layout and path geometry, while the fill color comes from the `RGB hex value` column. The visualization transitions from a loading message to the full color wheel once the data arrives.
