This example demonstrates how to load and parse CSV data using D3 v5 and modern JavaScript features. It fetches a CSV file containing CSS named colors from a GitHub gist and displays the file size in kilobytes, row count, and column count in large text. The implementation uses `d3.csv` for parsing, along with the Fetch API and `async`/`await` syntax for handling asynchronous requests. It also includes commented-out alternatives showing the pyramid-of-doom pattern and a `fetch`-based approach.
