This example demonstrates how React state and D3 can work together to asynchronously load and summarize a CSV dataset of CSS named colors. The app renders a text summary displaying the file size in kilobytes, row count, and column count once the data arrives. The code uses `d3.csv` inside a React `useEffect` hook to fetch the remote CSV, while `useState` manages the loading state. The final message is formatted using `d3.csvFormat` to calculate the data’s byte length, with ReactDOM rendering the result as SVG-adjacent text in a `<pre>` element.
