This example demonstrates how to load and parse CSV data using D3.js v7. The program fetches a CSV file of CSS named colors from a GitHub gist, then parses it with `d3.csv()` and displays summary statistics. The output shows the data size in kilobytes, the number of rows, and the number of columns in large text on a blank page. The code primarily relies on the `d3.csv` function for parsing and `d3.csvFormat` to calculate the data's byte size, with alternative fetch-based approaches commented out.
