This example displays a simple text message, "Hello VizHub!", centered on the page with a large font size. The code imports the `select` function from D3.js to target the `#message` div and sets its text content using the imported `message` string. It demonstrates a basic D3 selection and DOM manipulation pattern, with the message defined as an ES6 module export in `myMessage.js`. The styling is handled by external CSS, and the application runs entirely in the browser.
