This example demonstrates a minimal D3.js project that displays a message within an HTML page. The visualization initializes by selecting an HTML element with the ID "message" and populates it with text content. The implementation imports only the `select` function from D3 v5.9.1, which is loaded via a CDN script tag. The page layout is styled with an external CSS file that imports the Ubuntu font from Google Fonts. The example shows a basic setup for integrating D3 with standard HTML and JavaScript files, though no actual chart or dynamic data rendering is present in the provided code.
