Hello VizHub
This example renders a single, large, centered message ("Hello VizHub!") in a bold Ubuntu font against a dark background. It uses D3.js v5's `select` function to target the `#message` div and set its text content through the `text` method. The text string is imported from a local ES6 module (`myMessage.js`), demonstrating modular JavaScript structure within a simple D3 setup that prioritizes visual clarity over data-driven complexity.
