This example demonstrates how to load and parse a CSV file using D3 v7, displaying the file size in kilobytes, the number of rows, and the number of columns from the CSS named colors dataset. It uses the `d3.csv` method to fetch and parse the remote CSV, then `d3.csvFormat` to calculate the file size and the `data.columns` property to count attributes. The resulting summary is rendered as large text inside a `<pre>` element.
