This example visualizes the contents of a CSV file containing CSS Named Colors, displaying a summary message with the data size in kilobytes, row count, and column count. Built with React and D3.js v5, it uses D3’s `csv` function to fetch and parse the dataset asynchronously via a promise, updating the React state and rendering the result in a large `<pre>` element. The code demonstrates loading data with `useEffect` and `useState` hooks, along with D3’s `csvFormat` for byte calculation.
