This example demonstrates basic SVG shape rendering, showing overlapping circles, a diagonal line, a filled path, and a stroked path that draws an open polyline. The code uses raw SVG elements—`circle`, `line`, and `path`—directly in an HTML document, with CSS to hide page margins and overflow. Shapes are styled via inline attributes like `fill`, `stroke`, and `stroke-width`. A commented-out `rect` element remains in the source but is not displayed. The rendering relies solely on native SVG capabilities without additional JavaScript libraries.
