This example shows how React and D3 can be combined to load and summarize a CSV dataset. The React component uses the `useState` and `useEffect` hooks to fetch data asynchronously via `d3.csv` from a GitHub-hosted file of CSS named colors. Once loaded, the component displays the file size in kilobytes, row count, and column count using `d3.csvFormat` to calculate the byte length. While the page loads, it shows a "Loading..." message; after loading, the result is rendered as large text within an SVG-ready HTML structure.
