Hello VizHub
A minimal D3.js example displays the text “Hello VizHub!” centered on a dark blue background. The visualization uses the `d3.select` API to target a DOM element by ID and set its text content. The message originates from a separate ES6 module, `myMessage.js`, which exports the string. Styling relies on a linked `styles.css` with the Ubuntu font and a large font size. The example demonstrates basic D3 DOM manipulation and modular JavaScript without any data source or complex rendering.
