This example demonstrates how to create a basic D3.js visualization within VizHub, displaying a greeting message on a styled HTML page. The code uses D3’s `select` method to set the text content of a div element, importing local ES6 modules like `myMessage.js` to supply the message string. The page’s visual design is handled through CSS, including a custom Ubuntu font and dark blue background, while the HTML structure loads D3 v5 from a CDN and bundles all scripts for execution.
