This example displays the text “Hello VizHub!” centered in the viewport using a large font size. It demonstrates how to combine D3.js version 5 with ES6 modules, importing the `select` function from D3 via UNPKG and a custom `message` constant from a local file. The code uses `select('#message').text(message)` to set the content of a styled HTML div, showing basic DOM manipulation and modular JavaScript structure within a simple visualization scaffold.
