This example demonstrates the asynchronous loading of a CSV file in D3 version 7, using the `fetch` API to retrieve named color data from a GitHub Gist. The code defines an `async` function that awaits the network response and text parsing, then logs the raw CSV content to the console. The page itself displays the static text "Hello D3 version 6" set via `d3.select`, contrasting the simple DOM manipulation with the more complex data-fetching pipeline. The approach highlights modern promise-based syntax over older nested callback patterns.
