This example demonstrates the fundamentals of loading and parsing CSV data using D3.js version 5. It fetches the CSS Named Colors dataset from a GitHub Gist and displays a simple text summary of the file size in kilobytes, row count, and column count. The primary approach uses the `d3.csv` function to fetch and parse the remote CSV file, leveraging Promise-based asynchronous handling. The code also includes commented-out alternatives using native `fetch` with `async`/`await` and the `d3.csvParse` function, alongside a nested Promise "pyramid of doom" example. The output is rendered as large text within an HTML `<pre>` element.
