This example displays the text “Hello VizHub!” centered on a dark blue background using the Ubuntu font, styled with CSS. It demonstrates a minimal D3.js setup where the `select` function from D3 v5 targets a `div` element by ID and sets its text content. The message itself is defined as an ES6 module export in `myMessage.js`, illustrating how to import and use local modules alongside D3's API within a VizHub project.
