This example uses D3.js version 5 to display the text “Hello VizHub!” centered on a dark blue background. The page renders the message by selecting the `#message` div and setting its content with D3’s `select` function. Styling relies on an external Google Fonts stylesheet and a local CSS file that sets the font family, size, and colors. The code is organized into modular ES6 files, with the message text imported from a separate module.
