This example demonstrates how SVG shapes and CSS styling can be combined to create structured graphics. It shows circles, rectangles, lines, and paths arranged within a scalable group, using both inline presentation attributes and external stylesheet rules. The `styles.css` file applies stroke styles to line and path elements via class selectors, while inline `fill` and `stroke` attributes directly control individual shapes. SVG transform groups are used for positioning and scaling, enabling a layered composition. The rendering remains purely vector-based, relying on the SVG specification and CSS cascade without JavaScript libraries.
