This example demonstrates how to load a CSV dataset of CSS named colors using D3’s `d3.csv` utility within a React application, displaying a summary of the data’s size, row count, and column count via a formatted text message. The React component uses the `useState` and `useEffect` hooks to fetch the data asynchronously and manage its state, showing a “Loading…” placeholder until the promise resolves. The visualization renders as SVG but outputs only a text report, generated by a custom `message` function that formats the CSV metadata.
