This example demonstrates how to load external data in a React application using D3 utilities, displaying the dataset’s size in kilobytes, row count, and column count as formatted text. The code uses React’s `useState` and `useEffect` hooks to manage the asynchronous loading state, while `d3.csv` fetches the CSS named colors dataset from a GitHub gist. The `d3.csvFormat` function calculates the data size for the message. Rendering is handled through React DOM, producing an SVG-backed text output that transitions from a “Loading…” placeholder to the final statistics.
