This example demonstrates a minimal D3.js setup within VizHub, showing how to import D3 functions and local ES6 modules. The code uses `import { select } from 'd3'` to target the `#message` div and set its text content, while `myMessage.js` exports the string "Hello VizHub!" as the displayed message. The page renders a single centered heading with large typography defined in `styles.css`, supported by D3 v5 loaded from UNPKG. The example illustrates basic D3 DOM selection and text manipulation within a modular JavaScript structure.
