This example renders a pie chart of CSS named colors using React to generate the SVG. The code loads color data from a CSV file using D3's `csv` utility, then passes it to React, which maps each record to a `<path>` element. D3's `pie` and `arc` functions compute the angular segments, while the `fill` attribute uses the color's hex value. The visualization displays all colors as equal-sized slices, forming a full circle.
