This example demonstrates how to load and parse external CSV data using D3 v5. It fetches a text file from a GitHub gist URL using the Fetch API, then converts the raw text into an array of JavaScript objects with `d3.csvParse`. The parsed data is logged to the browser console, showcasing the basic pattern for retrieving and structuring tabular data for use in a visualization. No visual rendering occurs; the focus is purely on data acquisition and formatting.
