This example demonstrates fundamental SVG shapes rendered directly in an HTML document, including overlapping circles, a line, and two path elements. The visualization uses raw SVG markup with attributes like `cx`, `cy`, `r`, `fill`, `stroke`, `stroke-width`, and the `d` path syntax to define geometry. A commented-out `<rect>` element shows an alternative shape, while the main scene displays a horizontal bar path and a vertical polyline. The code relies on native browser SVG support, with a simple `<svg>` tag sized at 960 by 500 pixels and CSS to hide page overflow.
