This example renders a radial burst visualization of CSS named colors as an SVG, with each color occupying a slice of a circle. It loads color data from a CSV file using `d3.csv`, computes arc angles with `d3.pie`, and draws the paths with `d3.arc`. React manages the component state and lifecycle, using `useState` and `useEffect` to fetch the data asynchronously, while `ReactDOM` mounts the SVG into the DOM. The visualization fills each slice with the corresponding RGB hex value from the dataset.
