This example demonstrates how to load and display CSV data within a React application, showing the dataset's row count, column count, and size in kilobytes. The code uses React hooks (`useState` and `useEffect`) to manage asynchronous data fetching, while the `loadData` helper employs the Fetch API to retrieve a remote CSV file. D3's `csvParse` converts the raw text into a parsed data structure. The visualization updates from a loading message to the data summary once the fetch completes.
