This example demonstrates basic SVG shapes—circles, rectangles, lines, and paths—styled through both presentation attributes and an external CSS stylesheet. It shows how fill colors can be set directly on elements (e.g., red, `#83cc2a`) or inherited from a parent `<g>` group, with stroke properties controlling outlines. The CSS classes `.lines` apply stroke width and color, while the path uses the `stroke-linejoin` and `stroke-linecap` properties. The SVG structure employs `transform` attributes for scaling and translation, rendering vector graphics directly in the browser without additional JavaScript libraries.
