This example demonstrates how D3.js can be used to set text content on a webpage, displaying "Hello VizHub!" in a large, centered message. It loads D3 v5 from UNPKG and uses the `select` function from the d3 module to target a div element by ID. The code also showcases ES6 module imports, including a custom local module for the message string. The visualization is rendered through a simple HTML structure with external CSS styling.
