This example demonstrates loading external data into a React component using D3’s `csv` method. It fetches a CSV file of color names from a GitHub gist, then displays a summary of the data—including file size, row count, and column count—as text in a `<pre>` element. The React app uses the `useState` and `useEffect` hooks to manage the async data fetching and re-rendering once the data arrives. The visualization shows the loaded data’s metadata rather than a chart, highlighting how D3 and React integrate for data-driven interfaces.
