This visualization displays all 148 CSS named colors as a radial burst of pie slices, each colored by its hex value. The code loads the CSV data from a GitHub gist using `d3.csv`, then uses `d3.pie` to compute the angles and `d3.arc` to generate paths. React handles rendering with SVG, mapping each slice to a `<path>` element whose fill comes from the `RGB hex value` column. The example demonstrates a minimal integration of React state management with D3’s data-processing utilities.
