This example displays a simple, full-page text message, “Hello VizHub!”, centered on a dark blue background using an imported Ubuntu font. It demonstrates the basic structure of a D3.js v5 project within VizHub, showing how to modularize code by importing a message from a separate ES6 module and setting the text of an HTML element. The implementation uses D3’s `select` function to target the `#message` div and apply the text, with styling handled entirely by the external `styles.css` file.
