This example demonstrates a variety of basic SVG shapes—circles, rectangles, lines, and a path—styled through both inline attributes and external CSS. It shows how fill colors, stroke widths, and stroke-linejoin properties are applied directly to elements or via CSS classes like `.lines`. The visualization uses raw SVG markup within an HTML page, leveraging a `<g>` element with transforms for scaling and translation. The rendering relies solely on standard SVG APIs and CSS, with no JavaScript libraries involved.
