This example displays a simple, single-line text message, “Hello VizHub,” centered on a blank page. It uses D3.js version 5.9.1 loaded from a CDN to select a div element and append the text. The visualization demonstrates a minimal setup with separate HTML, CSS, and JavaScript files, where the D3 selection and data join are used to update the DOM. No external data source is involved; the message is defined directly in the JavaScript bundle.
