This example demonstrates fundamental SVG shapes as building blocks for data visualization. It generates a simple, empty SVG container on the page, illustrating the basic structure and rendering approach of SVG-based graphics. The code relies on the native SVG API, creating an `<svg>` element within the HTML document, without any additional JavaScript libraries or data sources. The example serves as a minimal starting point for understanding how SVG elements are inserted directly into the DOM for vector-based visual output.
