Hello VizHub
This example displays a large, centered "Hello VizHub!" message in a dark blue scene with Ubuntu typography. It demonstrates basic DOM manipulation and ES6 module imports within the VizHub environment. The code uses D3 v5 to load the library, standard JavaScript to set the text content via a `rep` element, and CSS for styling. The message originates from an exported constant in `myMessage.js`, while `index.js` also defines an unused "Hello World" variable. The visualization relies on static HTML, CSS, and modular JavaScript rather than dynamic data or canvas rendering.
