This example displays a simple "Hello VizHub!" message centered on the page. It uses D3 v6, specifically the `select` function, to set the text content of a div element with the id "message". The message string comes from a separate ES6 module, which is imported as a local dependency. Styling is handled through an external CSS file that applies large, centered font formatting. The visualization demonstrates a minimal setup for combining D3, ES6 modules, and CSS in a single-page web application.
