This example displays a large, centered “Hello VizHub!” message in blue against a dark navy background. The page uses D3 v5’s `select` method to set the text content of a `div` with the ID `message`. The message string is imported from a separate ES6 module (`myMessage.js`). Styling is handled by external CSS that imports the Ubuntu font from Google Fonts and applies a 12em font size. The visualization demonstrates basic D3 DOM manipulation without any data or complex rendering.
