This example renders a simple message, “Hello VizHub!”, centered on the page. It demonstrates basic D3.js usage by selecting a DOM element and setting its text content. The code imports the `select` function from D3 v5 via a CDN and also imports a local ES6 module (`myMessage.js`) that exports the message string. The display is styled with a large font size using a separate CSS file. The visualization shows how to combine local modules, external libraries, and styling in a single VizHub project.
