This example displays CSS named colors as horizontal stacked bars, with each row rendered as a div whose background color corresponds to the RGB hex value from the dataset. It uses React hooks (useState, useEffect) to fetch and store data loaded via d3.csv from a gist, and conditionally renders a loading message until the data arrives. The visualization maps each color record to a fixed-width, 4-pixel-high row, producing a dense, rainbow-like strip.
