This example demonstrates a minimal D3.js setup that renders the text “Hello VizHub!” inside a centered HTML div. It shows how to import functions from the D3 library using ES6 module syntax and also load a custom local module, myMessage.js, which exports the displayed string. The code uses `select` from D3 to target the `#message` element and update its text content. Styling is handled through an external CSS file, with the page initialized via a bundled JavaScript file.
