A simple D3.js example displays the text "Hello VizHub!" centered on a dark background with large, light-colored Ubuntu font. The visualization demonstrates basic DOM manipulation, using the `select` function from D3 v5 to target a div element and set its text content. An ES6 module named `myMessage.js` exports the message string, which is imported into the main `index.js` file. The styling comes from an external CSS file using a Google Fonts import.
