This example demonstrates basic SVG shapes—circles, rectangles, lines, and paths—styled with CSS. The code uses raw SVG elements within an HTML document, applying inline attributes like `fill` and `stroke` alongside a CSS class (`.lines`) to control appearance. A `<g>` element groups shapes with shared transform and style properties, while the SVG `scale` transform enlarges the entire drawing. No JavaScript libraries are used; rendering relies solely on SVG and CSS.
