This example shows CSS named colors as a single circular pie chart, with each color’s name as a tooltip on its corresponding arc. React (via `useState`, `useEffect`, and `ReactDOM.render`) manages the loading state and SVG rendering, while D3’s `csv`, `pie`, and `arc` utilities fetch the dataset and compute the arc paths. A `<clipPath>` with a circle clips the chart into a ring shape, and the code uses `d.data['RGB hex value']` for fills and `d.data['Keyword']` for IDs and titles.
