This example demonstrates a minimal "Hello VizHub!" visualization that displays a text message centered on the page using D3.js for DOM manipulation. The code imports the `select` function from D3 v5 and the `message` from a local ES6 module, then sets the text of an HTML div element. Styling is applied through an external CSS file that centers the message with a large font size. The visualization relies on D3's `select` API and local module imports to show basic VizHub functionality.
