This example demonstrates a minimal HTML page set up for data visualization. It loads D3 v5 from a CDN and includes an empty SVG element within the body, providing a starting point for building charts. The page centers its content via CSS and logs a simple message to the browser’s developer console using the `console.log` API. It relies solely on D3’s core library and standard HTML, with no visualization logic implemented yet, serving as a template for future projects.
