This example demonstrates the foundational use of SVG for creating vector graphics in a web page, with a focus on the `d3js` course context. The visualization shows a basic HTML document structure with an empty `<body>` element, indicating a starting point for SVG rendering. It uses the raw SVG API provided by the browser, with no additional JavaScript or D3.js functions invoked. The page renders a blank canvas, preparing for the drawing of shapes and paths by the user. The code is a minimal setup for learning SVG fundamentals.
