This example demonstrates how to load and display a summary of a CSV dataset using React and D3. It fetches the CSS named colors dataset from a GitHub gist via D3’s `csv` utility, stores the result in React state with `useState` and `useEffect`, and renders a formatted message showing the file size in kilobytes, row count, and column count. The visualization shows the loading process in a plain text `<pre>` element, relying on React’s rendering and lifecycle management.
