This example displays a single message, “Hello VizHub,” centered as large text. The visualization is built with D3.js v5, using the `select` API to target the `#message` div and set its text content. The page loads local CSS for styling and a bundled JavaScript file that imports the message from a separate module. The code also defines a constant and a regular expression, though these do not affect the displayed output. The rendering is a simple DOM-manipulation example rather than a data-driven graphic.
