This visualization displays the message “Hello VizHub!” in large, centered text on a plain background. It uses D3.js (version 6) and the `select` API to target the HTML `div` with the ID `message`, then sets its text content. The text is styled via an external CSS file, which applies a font size of 12em and center alignment. The example demonstrates a basic ES6 module structure, importing the message string from a separate JavaScript file and integrating it into the page.
