This example displays a simple “Hello VizHub!” message centered on the page using D3 v5. It demonstrates modular ES6 imports, including `select` from the D3 library and a local `message` constant from `myMessage.js`. The D3 `select` API targets the `#message` div and sets its text content, while CSS styles the text size and alignment. The HTML loads D3 from UNPKG and references a bundled JavaScript file, showcasing basic integration of external and local modules in a visualization setup.
