This example demonstrates the modular workflow of VizHub, showing how to combine D3.js with local ES6 modules to create a simple interactive page. The code loads D3 v5 from a CDN and uses `import { select } from 'd3'` to manipulate the DOM, setting the text of a `#message` div to display "Hello VizHub!" from the exported `message` variable in `myMessage.js`. The page also includes CSS styling for centered, large text. It illustrates the basic structure of a VizHub visualization project, including HTML, JavaScript, and stylesheet files.
