This example visualizes CSS named colors as a radial burst, with each color represented as a slice of a pie chart, creating a circular spectrum of color swatches. It loads the data from a CSV file using D3’s `csv` utility, then uses React with hooks (`useState`, `useEffect`) to fetch and render the SVG. The pie slices are computed with D3’s `pie` and `arc` functions, drawing each `path` with the fill set to the hex value from the data.
