Hello VizHub
This example displays the text "Hello VizHub!" centered on a dark blue background using the Ubuntu font, serving as a minimal demonstration of the VizHub platform’s capabilities. The page is built with a simple HTML structure that loads D3.js v5 and a local stylesheet, while the JavaScript imports the `select` API from D3 to set the text of a specific div element. The message itself comes from a separate ES6 module, showcasing modular code organization within the framework.
