This visualization displays the CSS named colors as a donut chart, with each color represented by a single wedge of equal size. The chart uses D3’s `arc` generator to compute the SVG path for each slice, with angles evenly distributed across the full circle. Data is loaded from a CSV file using D3’s `csv` utility, and the chart is rendered in a React application with SVG elements, where each wedge’s fill is set to the corresponding RGB hex value from the dataset.
