This example demonstrates basic geometric shapes constructed with SVG elements, including circles, rectangles, lines, and paths. It shows how graphical primitives can be styled with fill colors and strokes, and grouped and transformed using SVG’s `g` element with `scale` and `translate` attributes. The code uses raw SVG markup inside an HTML document, with CSS classes like `.lines` to control stroke properties. A simple path with rounded line joins illustrates polyline rendering within the scaled coordinate space.
