This example demonstrates the basics of loading and parsing CSV data using D3 v7. It fetches a CSS Named Colors dataset from a GitHub gist and displays the number of columns and rows in a large text element. The code uses `d3.csv()` to asynchronously retrieve the data, then accesses the `columns` property and array length to generate the summary message. The result is rendered into an HTML `<pre>` container using the DOM API `textContent`.
