This example demonstrates the minimal structure of an SVG scene within an HTML page, using no external libraries. It renders an empty document with a `<body>` element styled by CSS and enhanced by JavaScript, highlighting the foundational layers of web-based visualization. The code sets up a blank canvas where SVG elements can be added programmatically, serving as a starting point for interactive graphics. It relies solely on native HTML, CSS, and JavaScript APIs, with no data source or rendering pipeline beyond the bare document structure.
