This example demonstrates a minimal webpage that displays a greeting message using D3.js version 5. The visualization shows the text “Hello VizHub!” centered on the page, with styling applied via an external CSS file. The code imports the `select` function from D3 to target the message div and set its text content, while a local ES6 module provides the message string. The HTML loads D3 from a CDN and bundles the JavaScript through a separate `bundle.js` file.
