This example shows a radial burst of MDN CSS color swatches, with each named color rendered as a wedge around a central point. React manages the component state and lifecycle, using the `useEffect` hook to load the CSV data via D3’s `csv` method, while `d3.pie` and `d3.arc` compute the wedge geometry. The SVG paths are filled with the hex values from the dataset, and a loading message appears until the data arrives.
