This example demonstrates a concise display of metadata about a dataset of CSS named colors, showing the file size in kilobytes, row count, and column count as plain text. The React component uses the `useState` and `useEffect` hooks to manage asynchronous data loading, while D3’s `csv` function fetches the remote CSV file. The `d3.csvFormat` utility calculates the data size, and ReactDOM renders the result, displaying “Loading...” until the data arrives.
