This example demonstrates a minimal D3.js setup that renders a personalized greeting message centered on the page. It uses D3’s `select` API from the `d3` module to target the `#message` div and set its text content via the `.text()` method. The message string comes from a local ES6 module (`myMessage.js`), while styling is applied through an external CSS file. The visualization highlights how to combine D3, local imports, and CSS within a simple web page.
