This example demonstrates how SVG shapes can be styled and transformed using both inline attributes and CSS. It shows circles, rectangles, lines, and a path, with some shapes grouped to share fill and stroke properties, while the `lines` class applies black strokes and a rounded line join. The SVG viewport scales up by 1.5, and a translated group shifts lines and paths into place. The code uses raw SVG elements and CSS rules, with no external JavaScript libraries.
