This example shows how to load a CSV file of CSS named colors into a React application and display summary statistics about the dataset. The code uses React hooks (`useState`, `useEffect`) to fetch the data asynchronously with D3’s `csv` function, then renders a formatted message showing the file size in kilobytes, row count, and column count using `d3.csvFormat`. The visualization is minimal—a large `<pre>` element that displays either “Loading...” or the computed statistics after the data arrives from a GitHub gist URL.
