This example shows CSS named colors from a CSV file rendered as a radial burst of arcs, with each color’s hex value directly filling its corresponding path. The code uses React’s `useState` and `useEffect` to fetch the data via D3’s `csv`, then computes arc angles with `d3.pie` and draws the shapes using `d3.arc`. All geometry is output as SVG elements inside a React component, with loading state handled before rendering.
