This example demonstrates basic SVG shapes and styling through CSS, using circles, rectangles, lines, and paths within a single scalable vector graphic. The SVG is rendered directly in an HTML document, with the `<g>` elements grouping shapes to apply transformations and shared styling. CSS classes like `.lines` define stroke properties for the line and path elements, while inline attributes set fill colors and stroke widths. The visualization shows how SVG’s coordinate system and CSS work together to control shape appearance and positioning, with a scale transform applied to the entire group.
