This example demonstrates basic SVG shape rendering within an HTML page, organizing circles, rectangles, lines, paths, and polygons in nested groups. The SVG canvas scales the entire composition with a `transform` attribute, while a second group applies a further scale to the polygon. Cascading style sheets define red stroke styling for the `.lines` class, including a darkened path with rounded joins and caps, plus a light-blue stroked, dark-blue filled polygon. The code uses raw SVG elements—`circle`, `rect`, `line`, `path`, `polygon`—with inline attributes for fills, strokes, and coordinate positions, showing static vector graphics without external libraries.
