This example showcases basic SVG shapes—circles, rectangles, lines, and a path—styled with CSS and grouped using SVG’s `<g>` element. It demonstrates how fill colors, stroke widths, and transforms like translation and scaling affect shape rendering. The code uses raw SVG markup within an HTML file, linked to an external stylesheet that applies classes to set stroke properties. No JavaScript libraries are used; rendering relies entirely on the browser’s native SVG support.
