This example demonstrates a minimal D3.js visualization that displays the text “Hello VizHub!” in a large, centered Ubuntu font on a dark blue background. It shows how to structure a simple web page using HTML, CSS, and ES6 modules, with D3’s `select` method updating the text content of a designated div element. The page imports D3 from a CDN and uses a local module to export the message string, illustrating basic data-binding and modular code organization within the VizHub framework.
