This example demonstrates fundamental SVG shapes and CSS styling within a React starter template. It renders circles, rectangles, lines, and a path inside an SVG element with a scale transform, showcasing fill colors, stroke properties, and stroke-width attributes. The code applies CSS classes to style grouped elements, such as the `.lines` class adding black strokes to lines and paths, while inline attributes like `fill="red"` and `#83cc2a` set explicit colors. The visualization relies on plain SVG markup and external CSS rules to control appearance.
