This example visualizes CSS named colors as a radial burst of pie slices, each colored by its corresponding hex value. The visualization loads data from a CSV file using D3's `csv` utility, then uses React to render an SVG containing the pie chart. The pie layout is computed with D3's `pie` function, while each slice is drawn as an SVG path using the `arc` generator. The React component manages state and renders the final visualization, with a simple loading message shown before data arrives.
