Hello VizHub
This example demonstrates a minimal VizHub project that displays the text “Hello VizHub!” on a dark blue background. The page uses D3.js v5’s `select` function to target the `#message` div and set its text content, while an ES6 module exports the message string. Styling comes from an external CSS file that imports the Ubuntu font from Google Fonts, sets the body’s background color, and applies a large font size. The code illustrates the basic workflow of combining D3 API calls with modular JavaScript in a VizHub environment.
