This example displays the full CSS color palette as a circular pie chart, with each color occupying an equal slice. It clearly shows the distribution and visual relationships among all named CSS colors. The code loads color data from a GitHub-hosted CSV file using `d3.csv`, then computes each slice’s angles with a `d3.arc` generator. React handles rendering by mapping over the data to create SVG `<path>` elements, with the fill set to each color’s hex value. The visualization updates once the asynchronous data fetch completes.
