The example demonstrates how SVG shapes—circles, rectangles, lines, and paths—are styled with inline attributes and CSS classes to create a colorful, layered composition. It shows grouped elements inheriting fill and stroke properties, while a dedicated `.lines` class applies thicker stroke styling to line and path elements. The code uses plain SVG markup within an HTML document, with CSS rules controlling the body margin and line appearance, and applies a scaling transform to the entire group for visual emphasis.
