Hello VizHub
This example demonstrates VizHub’s ability to render a simple, text-based visualization using a modular ES6 structure. It shows a static message, “Hello VizHub!”, displayed prominently on a dark blue background with large, centered Ubuntu font styling. The code loads D3 v5 from a CDN, although the active script comments out the `select` import and instead relies on `bundle.js` to wire up the page. Styling comes from an external `styles.css` file, and the example illustrates how HTML, CSS, and JavaScript modules can be organized within a project.
