This example demonstrates how to load a remote dataset of CSS named colors using D3’s `csv` utility, with React state managing the asynchronous fetch. The interface displays a plain-text summary reporting the file size in kilobytes, the number of rows, and the column count, refreshing once the data arrives. The code combines React’s `useState` and `useEffect` hooks, D3’s `csv` for parsing, and a custom `message` helper that formats the summary, all rendered as SVG-free `<pre>` output.
