Hello VizHub
This example demonstrates a minimal D3.js visualization that displays the text “Hello VizHub!” prominently on a dark, styled webpage. It shows how to combine an ES6 module with D3’s `select` method to update the content of an HTML `<div>` element. The code imports the `message` string from a local module, then uses D3 to set that text inside the `#message` div. Styling is handled via external CSS, importing the Ubuntu font and applying a large font size, centered layout, and a navy background.
