This example demonstrates a minimal React application that loads a dataset of CSS named colors from a remote CSV file and displays its key statistics. The code uses React hooks, specifically `useState` and `useEffect`, to manage asynchronous data loading, while the `csv` function from D3 v5 fetches and parses the file. After loading, a text summary shows the file size in kilobytes, row count, and column count, using `d3.csvFormat` to compute the byte length. During the fetch, a simple "Loading..." placeholder is rendered, highlighting the interplay between React state and D3's data utilities.
