This example displays a single, large "Hello VizHub!" message in the center of a dark blue page, styled with the Ubuntu font. It demonstrates a minimal D3.js setup by using `select` to set the text content of a `div` element, pulling the string from a separate ES6 module. The visualization relies on an external D3 v5 script loaded via CDN and imports the `message` variable from `myMessage.js` to populate the view, with all styling defined in a linked stylesheet.
