This example demonstrates how to load and display metadata about CSS named colors using React’s `useState` and `useEffect` hooks alongside D3’s `csv` utility. The React component fetches a CSV file from a GitHub gist, stores the parsed data in state, and renders a text summary showing the data’s size in kilobytes, number of columns, and row count. The summarized message is generated by the `message` function using D3’s `csvFormat`. The visualization appears as plain text in a `<pre>` element, updated dynamically once the data loads.
