A collection of basic SVG shapes—a circle, a rectangle, and a polyline path—rendered with inline SVG elements and styled via external CSS. The example demonstrates how CSS classes control stroke color, width, and fill, including a blue path with rounded line joins. It uses raw SVG tags like `circle`, `rect`, `line`, and `path`, with a transform applied to scale and translate the group. The code exercises standard SVG geometry and CSS styling rules without any JavaScript or additional libraries.
