This example demonstrates how to load a CSV file from a remote URL using D3’s `d3.csv` method and manage the resulting data state with React’s `useState` and `useEffect` hooks. It displays a summary of the loaded dataset—file size in kilobytes, row count, and column count—inside a `<pre>` element. The data comes from a GitHub Gist containing CSS named colors. React renders the message while the data is loading or after it arrives, showing the integration between D3’s data loading utilities and React’s component lifecycle.
