This example demonstrates fundamental SVG shapes through a simple static composition. It shows two overlapping circles in red and green, a navy diagonal line, a horizontal path forming a rounded rectangular shape, and a black polyline with a sharp corner. The visualization uses raw SVG elements embedded directly in HTML, including `<circle>`, `<line>`, and `<path>`, all rendered with explicit coordinates and styling attributes. The code relies solely on the native SVG API without additional JavaScript libraries, and the rendering is entirely vector-based.
