This example visualizes the CSS named colors as a radial burst of pie slices, each filled with its corresponding RGB hex value. The visualization uses D3’s `csv` loader to fetch color data from a gist, and React’s `useState` and `useEffect` hooks manage the asynchronous data loading. The pie layout is computed with `d3.pie`, and each slice is rendered as an SVG `<path>` using `d3.arc` with an inner radius of zero, creating a full circle of color segments around a central point. React-DOM mounts the SVG into the page, with a loading fallback until data arrives.
