This example demonstrates how to load and parse CSV data using D3 v5 in a React application. It displays the file size, row count, and column count of a CSS Named Colors dataset fetched from a GitHub gist. The code uses `d3.csv` to fetch and parse the data, then calculates metrics with `d3.csvFormat` and `data.columns.length`. An alternative approach using the Fetch API, `async/await`, and `d3.csvParse` is included as commented-out code. The results render into a large-text `<pre>` element via `textContent`.
