Hello VizHub
This example demonstrates VizHub’s basic workflow by rendering the text “Hello VizHub!” in large, centered, brightly colored lettering against a dark blue background. The visualization uses D3.js v5’s `select` method to set the text content of an HTML `div` element, while the message itself is imported from a separate ES6 module (`myMessage.js`). The page layout and typography are styled with a linked CSS stylesheet that loads the Ubuntu font from Google Fonts. No interactive behavior or data processing is shown.
