This example displays a centered, large-font message, "Hello VizHub!," as a minimal demonstration of integrating D3.js with ES6 modules. It uses D3’s `select` method to target a div element and set its text content, with the string imported from a separate module. The layout is styled via an external CSS file, and the page loads D3 v6 from a CDN. The code serves as a simple template for building interactive visualizations within the VizHub environment.
