This example demonstrates how SVG shapes—circles, rectangles, lines, and a path—can be styled using external CSS. It shows that SVG elements inherit presentation attributes from CSS classes and parent groups, with the `.lines` class applying a red stroke and width to lines while the path overrides its stroke color. The code uses native SVG elements with the `transform` attribute for scaling and translation, alongside a linked `styles.css` file. Rendering is purely SVG-based without JavaScript libraries.
