This example demonstrates loading and parsing a CSV dataset of used car details using D3.js v7 within a React-based HTML page. It displays a summary message indicating the dataset’s size in kilobytes, row count, and column count after the file is fetched. The code relies on `d3.csv` to asynchronously retrieve the remote CSV, `d3.csvFormat` to measure its size, and DOM manipulation via `getElementById` to render the results. The page also includes an embedded SVG illustration and styled headings.
