This example demonstrates fundamental SVG shapes—overlapping red and green circles, a navy line, a black path with a fill, and a partially commented-out rectangle—rendered directly in an HTML document. The SVG markup uses standard shape elements like `<circle>`, `<line>`, and `<path>`, with attributes controlling position, size, fill, and stroke. No external libraries are used; the visualization relies solely on the browser’s native SVG rendering, as specified in the embedded wiring. The code includes a commented-out `<rect>` element, showing a static demonstration of basic vector graphics.
