This example demonstrates a minimal D3.js visualization that renders a static message, “Hello VizHub!”, centered on the page. It shows how D3 can be used for basic DOM manipulation, using the `select` API to target an HTML element and set its text content. The project also illustrates the use of ES6 modules, with the message string imported from a separate file, and a local CSS file for styling. The code loads D3 version 5.9.1 from a CDN.
