This example displays a simple text message, “Hello VizHub,” centered on a dark blue background with a large Ubuntu font. It shows how to set up a basic D3.js v5 project within the VizHub environment. The code imports the `select` function from D3 to target the `#message` element and uses a local module, `myMessage.js`, to supply the text content. Styling is applied via an external CSS file that imports the Ubuntu typeface from Google Fonts.
