This example demonstrates how to combine React state with D3’s data-loading utilities. It fetches a CSV file containing CSS named colors from a GitHub gist using `d3.csv`, then displays the dataset’s size, row count, and column count in a large HTML `<pre>` element. The React component uses the `useState` and `useEffect` hooks to manage asynchronous data fetching and trigger a re-render once the data arrives. The code also relies on `d3.csvFormat` in `message.js` to calculate the data size in kilobytes, showcasing a simple React–D3 integration pattern.
