This example demonstrates fundamental SVG shapes, including rectangles, circles, and ellipses, rendered directly in an HTML document. It shows how basic vector graphics are constructed using standard SVG elements within the body of a webpage. The visualization uses the native SVG API via inline markup in the `index.html` file, with no external JavaScript libraries or data sources. The page is intentionally minimal, focusing purely on the static presentation of geometric primitives without any interactivity or dynamic behavior.
