This example displays all CSS named colors as horizontal stripes, loading color data from a CSV file using d3.csv. The React component uses the useState and useEffect hooks to fetch the data and render each row as a colored div element. The app shows a loading message until the data arrives, then maps over the array to create stacked color bands with heights of 5 pixels each. The implementation combines React's declarative rendering with D3's data loading utilities (d3.csv) and demonstrates the message export that reports file size, row count, and column count.
