This example demonstrates a minimal D3.js visualization that displays the text "Hello VizHub!" on a webpage. The code uses the D3 `select` API to target a `div` element with the ID `message` and sets its text content. The message itself is defined as an ES6 module exported from a separate `myMessage.js` file. Styling is applied via a linked CSS file that imports the Ubuntu font and uses a dark blue background with light text.
