This example demonstrates loading and parsing a CSV file using D3.js version 7. It fetches data from a GitHub Gist containing CSS color codes, then displays the file size in kilobytes, row count, and column count in a large pre-formatted text block. The code uses `d3.csv()` to fetch and parse the data, `d3.csvFormat()` to calculate the raw file size, and `data.columns` to determine the number of columns.
