This example demonstrates a minimal D3.js setup, rendering the text “Hello VizHub!” centered on a dark blue page with large, styled typography. It imports the `select` function from D3 to set the text content of a `div` element, while a separate ES6 module exports the message string. The page’s appearance is controlled entirely through CSS, including a custom Ubuntu font loaded from Google Fonts. The visualization serves as an introductory template for using D3 with modular JavaScript and external styles.
