This example demonstrates a minimal React application that fetches and summarizes a dataset of CSS named colors. The visualization displays three key statistics about the loaded data: the approximate file size in kilobytes, the total number of rows, and the number of columns. The code uses React’s `useState` and `useEffect` hooks to manage the asynchronous loading process, while D3’s `csv` function retrieves and parses the data from a remote URL. Once loaded, the `message` helper formats the summary using D3’s `csvFormat` method, and the result is rendered inside an HTML `<pre>` element with large typography.
