This example demonstrates a collection of basic SVG shapes—circles, rectangles, lines, and a polyline path—styled through both inline attributes and an external CSS stylesheet. It shows how fill colors, stroke widths, transparency, and geometric transforms like scaling and translation apply to grouped elements. The visualization uses raw SVG markup within an HTML document, with CSS classes controlling line styles and joint/endpoint rounding. No JavaScript libraries are involved; the rendering relies entirely on the browser's native SVG support and CSS styling rules.
