This example displays the text "Hello VizHub!" in a large, centered message on a steelblue background, styled with the Ubuntu font. It demonstrates a basic D3.js v5 setup using the `select` function to update the DOM, while an SVG rect is drawn as a decorative block. The code imports a local ES6 module, `myMessage.js`, to supply the text, and renders the visualization as static SVG within an HTML page.
