This example shows how SVG shapes, including circles, rectangles, lines, and paths, can be styled with colors, strokes, and transforms. A group with a fill and stroke applies consistent styling to its child elements, while a CSS class sets stroke width, linejoin, and linecap on the path. The drawing uses inline SVG markup within an HTML document, with a linked stylesheet controlling layout and class-based stroke properties. No JavaScript libraries are used; rendering relies entirely on native SVG and CSS.
