This example displays the text “Hello VizHub!” centered on a dark blue background, demonstrating the basic structure of a D3.js visualization project. It uses d3.select to target a div with the ID “message” and sets its text content to a value imported from a separate ES6 module. The page is styled with CSS, including a custom Ubuntu font from Google Fonts and a large font size, while the HTML loads D3 v5 and the bundled JavaScript.
