This example demonstrates basic SVG shape construction, showing how circles, lines, and paths render in a fixed 960×500 canvas. It includes overlapping red and green circles, a navy diagonal line, a custom curve path, and an open polyline path drawn with a black stroke. The code uses raw SVG elements—`circle`, `line`, and `path`—with inline attributes for coordinates, colors, and stroke widths. A commented rectangle element shows alternative shapes not currently displayed. The SVG is embedded directly in the HTML body with CSS removing page margins and overflow.
