This example displays a simple web page with the text "Hello VizHub!" centered on the screen. The visualization is minimal, consisting only of a static greeting message. The code uses D3.js version 6, specifically the `select` API, to target the HTML element with the ID `message` and set its text content. The styling is defined in a separate CSS file with a large font size and centered alignment. The implementation imports a local ES6 module to provide the greeting string.
