This example displays a simple, centered greeting by rendering a text message on a web page. The visualization demonstrates a minimal D3.js setup, using the `select` API to target an HTML element and update its content. The text itself is imported from a separate ES6 module, highlighting basic code modularity. The page’s styling is managed through a linked CSS file, while the D3 library is loaded from a CDN, providing a foundational template for building more complex charts.
