This example uses raw SVG elements to demonstrate fundamental shapes and layering. Overlapping red and green circles show how later elements render on top, while a navy line, a custom curved path, and a black polyline illustrate the `path` drawing syntax directly in SVG. The code uses static SVG markup with attributes like `cx`, `cy`, `r`, `d`, `stroke`, and `fill`, and no JavaScript libraries are involved. The rendering approach is purely declarative SVG within an HTML page.
