This example shows a collection of simple geometric shapes—an ellipse, a rectangle, and a vertical line—positioned within an SVG canvas. The shapes are grouped and scaled using the `transform` attribute, with the line receiving a red stroke color via inline CSS. The rendering relies on raw SVG elements and CSS styling, with the `.lines` class defined in an external stylesheet, though the displayed elements primarily use inline presentation attributes. The code uses standard SVG APIs (`ellipse`, `rect`, `line`) and CSS for styling, with no external libraries.
