This example displays all named CSS colors as a radial burst, with each color represented as a slice of a pie chart emanating from the center. It loads color data from a CSV file using `d3.csv`, then uses React’s `useState` and `useEffect` hooks to manage the asynchronous data fetching. The visualization renders SVG paths via React, with `d3.pie` and `d3.arc` computing the slice angles and geometry. Each path’s fill is set directly from the CSV’s RGB hex value column.
