This example displays the text “Hello VizHub!” prominently in a large, bright font against a dark background. It demonstrates a minimal D3.js setup where the DOM element’s content is set programmatically. The code uses `select` from D3 v5 to target the `#message` div and updates its text with a string imported from a separate ES6 module (`myMessage.js`). Styling is handled via an external CSS file, with the body configured for centered, large-scale typography.
