This example demonstrates a minimal VizHub project that displays a centered "Hello VizHub!" message using D3.js v5. The visualization shows how to load D3 via UNPKG and combine it with local ES6 modules, importing the `select` function from D3 and a custom `message` constant from `myMessage.js`. The message text is set using D3’s `select` method on the `#message` div, styled with a 12em font size from the linked CSS file.
