This example displays all named CSS colors as a radial burst, with each color rendered as a slice of a pie chart. It loads the color data using `d3.csv`, then sorts and maps it with `d3.pie()` before drawing each arc with `d3.arc()`. React manages the component state and rendering, while D3 handles the data loading and geometry calculations. The visualization uses SVG via React's `path` elements, with each slice filled by its corresponding hex value from the dataset.
