This example displays the text “Hello VizHub!” centered on the page using D3.js. It imports the `select` function from D3 via UNPKG and a local ES6 module named `myMessage.js` that exports the message string. The code uses D3’s `select` to set the text content of the HTML element with the ID `message`, styled by an external CSS file. The example demonstrates basic D3 integration, local module imports, and CSS styling within a simple HTML page.
