This example demonstrates the fundamental SVG shapes—circles and rectangles—styling through both inline attributes and CSS classes. It shows how presentation properties like fill, stroke, and stroke-width can be defined either directly or via a stylesheet. The code applies a scale transform to the entire group, then a translate with a grouped color and stroke style, and finally a path with a round stroke-linejoin. The `.lines` class in `styles.css` sets stroke appearance, while `index.html` uses standard SVG markup within an HTML document.
