This example displays a summary of CSS named color data loaded from a remote CSV file, showing the file size, row count, and column count. The visualization uses React state management with the `useState` and `useEffect` hooks to fetch and store the dataset, while D3's `csv` function handles parsing the remote data source. The resulting text is rendered in a large `<pre>` element, and the summary metrics are computed using `d3.csvFormat` and the data's array properties.
