This example demonstrates how to load and summarize a CSV dataset of CSS named colors using React and D3. The app fetches the data via D3’s `csv` function within a React `useEffect` hook, then displays a text message indicating the number of columns, rows, and file size in kilobytes. The rendering is a simple SVG-based React component that shows the loading state until the data arrives, relying on the `d3.csvFormat` method to calculate the data size.
