This example visualizes CSS named colors as a radial pie chart, with each color represented by a slice of equal angular width. The visualization loads color data from a CSV file using the `csv` utility from D3 v5, then renders the chart as SVG paths using React components. React's `useState` and `useEffect` hooks manage the asynchronous data loading, while D3's `arc` generator computes each path’s geometry based on the data’s index. The chart displays the entire color spectrum arranged around a central point, with fill colors taken directly from the hex values in the dataset.
