This example displays a centered "Hello VizHub!" message in large, bold text, using D3.js version 6. The code imports the `select` function from D3 and applies it to set the text content of a `div` element with the ID `message`. The actual text comes from a separate ES6 module, `myMessage.js`, which exports a string constant. Styling is handled through an external CSS file that centers the text and sets the font size to 12em. The visualization serves as a minimal starter template demonstrating basic D3 DOM manipulation with modular JavaScript structure.
