This example demonstrates the basic interactive and rendering capabilities of VizHub, showing a message displayed prominently on a page. The code loads D3 v5 directly from the UNPKG CDN and demonstrates how to import specific D3 API functions like `select` to manipulate the DOM. It also showcases the use of local ES6 modules by importing a message string from `myMessage.js`. The D3 `select` function targets an HTML `div`, setting its text content, while CSS styles the text for large, centered presentation.
