This example demonstrates how to load and parse CSV data using D3 v5 and the Fetch API. It fetches the CSS Named Colors dataset from a GitHub gist and displays the raw text in the browser console. The code includes multiple commented-out approaches, showing alternatives like `d3.csv` for direct parsing and the newer async/await syntax with `fetch` and `response.text()`. It highlights the progression from callback-based "pyramid of doom" patterns to modern promise chains.
