This example demonstrates basic SVG shapes—circles, rectangles, lines, and paths—styled through CSS classes and inline attributes. It shows how fill colors, stroke widths, and stroke-linejoin properties affect rendering, with groups applying transforms like scaling and translation. The code uses raw SVG elements within an HTML page, alongside a linked stylesheet that sets stroke styling for grouped line elements. No external libraries are involved, and the rendering relies purely on native SVG support in the browser.
