This example displays a large, centered greeting message using D3.js. The code selects a div element and sets its text content from a separate ES6 module, demonstrating modular JavaScript with D3’s `select` function. The page uses a dark background with a light Ubuntu font, and the greeting is rendered at a massive font size for visual impact. The visualization is minimal, focusing on the integration of D3 for DOM manipulation and text updates within a custom stylesheet setup.
