This example demonstrates how to load and parse CSV data using D3 v5 and the Fetch API. It shows a large preformatted text element displaying the CSV file’s size in kilobytes, row count, and column count, derived from a gist containing named CSS colors. The code uses `d3.csv` to fetch and parse the data, `d3.csvFormat` to measure its length, and `d3.csvParse` for manual parsing, alongside plain `fetch` calls that log the raw text to the console.
