This example displays a single bold "Hello VizHub!" message centered on a dark blue page. It demonstrates the basic structure of a VizHub project, using D3.js v5’s `select` method to update the text content of a `div` element. The message originates from a separate ES6 module, `myMessage.js`, and the page’s styling relies on the Ubuntu font imported via CSS. The code highlights modular JavaScript imports and D3’s DOM manipulation alongside external stylesheet linking.
