This example displays a large, centered greeting—"Hello VizHub!"—in bright text against a dark blue background, styled with the Ubuntu font. It demonstrates fundamental VizHub capabilities, including importing D3.js functions and local ES6 modules. The code uses `d3.select` to set the text content of an HTML `<div>` element, sourced from a separate `myMessage.js` module, with styling applied via an external CSS file.
