This example demonstrates how VizHub integrates D3.js with modern ES6 module syntax. It loads D3 v5 from UNPKG and uses the `select` function to update the text content of a `<div>` element, displaying the message "Hello VizHub!". The visualization also imports a local ES6 module to supply the message string, while a CSS rule centers and scales the text. The example primarily showcases basic DOM manipulation with D3 and modular JavaScript organization rather than data-driven rendering.
