This example shows a minimal web page that displays the text “Hello VizHub!” centered on the screen. It loads D3 v5 from the UNPKG CDN and uses the `select` API to target a `<div>` element, setting its text content. The message string is imported from a local ES6 module (`myMessage.js`), demonstrating modular code organization. Styles are applied via an external CSS file, controlling the font size and alignment. The example focuses on basic D3 DOM manipulation and local module imports.
