This starter example displays the text "Hello D3" prominently in the center of a web page, serving as a minimal introduction to building visualizations with D3 version 6. It loads the D3 library from a CDN and uses the `select` function to target the body element, then calls the `text` method to inject the static string into the DOM. The page is styled with large, centered typography, and the accompanying video walks through the setup process. The example demonstrates the fundamental pattern of selecting a DOM node and manipulating its content with D3’s data-join-independent API.
