This example displays all CSS named colors as a circular color wheel, with each color occupying a wedge-shaped slice. Using React hooks to load and store the dataset, the visualization maps the data to SVG paths computed with D3’s `arc` and `pie` functions. The pie chart starts at the 12 o’clock position and renders each color’s hex value as its fill. The code references the CSS colors CSV from a GitHub gist and sets the outer radius to the full chart width.
