This example demonstrates a minimal React & D3 workflow for fetching and summarizing a remote CSV dataset. It loads the CSS named colors data from a GitHub gist using D3’s `csv` function, then stores the parsed result in React state via `useState` and `useEffect`. The rendered output is a `<pre>` element that displays a text summary—file size in kilobytes, row count, and column count—computed through the custom `message` function using `d3.csvFormat`.
