This example displays a single message, "Hello World," in a centered `<pre>` element. It demonstrates modular JavaScript by importing a separate message, "Hello VizHub!," from a local ES6 module via `myMessage.js`. The code loads D3 v5 from UNPKG, though it does not use any D3 functions for visualization. The page structure is defined in `index.html`, with styling applied through `styles.css`.
