This example displays the text “Hello VizHub!” prominently on a dark blue background, centered in a large Ubuntu font. It demonstrates how to structure a basic D3.js project within the VizHub environment by separating concerns into an HTML entry point, a stylesheet, and modular JavaScript files. The visualization uses D3’s `select` function to target the `#message` div and set its text content, while the message itself is imported from a local ES6 module (`myMessage.js`). The project loads D3 v5.9.1 from a CDN.
