This example demonstrates the fundamental capability of VizHub: a web page that displays a simple text message using D3.js version 5. The visualization shows a large, centered "Hello VizHub" text in a dark blue background with a custom Ubuntu typeface, loaded via Google Fonts. The code uses D3’s `select` function to target the `#message` div and set its text content, which is imported from a local module named `myMessage.js`. The styling is handled entirely through an external `styles.css` file, defining the background color, text color, alignment, and font size.
