This example demonstrates the basic workflow of loading and parsing a CSV file with D3 version 7 in a React application. It fetches a remote dataset of CSS named colors, then displays a text summary showing the file size in kilobytes, the number of rows, and the number of columns. The code uses `d3.csv` to retrieve and parse the data, `d3.csvFormat` to measure its size, and React hooks like `useState` and `useEffect` to manage the asynchronous loading process.
