This example displays a single, centered message using the D3.js library, reading its text from a separate ES6 module. It demonstrates how to combine D3 with modular JavaScript and external CSS styling. The page creates a div element and uses the `select` function from D3 to set its text content, while the `styles.css` file controls its large, centered typography. The project serves as a minimal template for integrating D3 v6 into a broader web application structure.
