This example greets the user with a large, centered "Hello VizHub!" message on a deep blue background, using the Ubuntu typeface. It imports the `select` function from the D3.js v5 library and an ES6 module `myMessage.js` that exports the displayed string. The page structure comes from `index.html` with a `message` div, styled by `styles.css`, and labeled with a 12em font size.
