Hello VizHub
This example renders a simple text message, "Hello VizHub!", centered on a dark blue page using the Ubuntu font. It demonstrates the basic structure of a VizHub project, showing how to combine an HTML container, a CSS stylesheet, and ES6 modules. The JavaScript imports the `select` function from D3 v5 to target the `#message` div and set its text content from a separate `myMessage.js` module, illustrating modular code organization.
