This example showcases basic geometric shapes drawn with SVG and styled using CSS, including circles, rectangles, lines, and a path. The shapes demonstrate grouping and transformation via SVG `<g>` elements, with one group applying translation and fill overrides, while another uses CSS classes for stroke styling. The code uses raw SVG markup within JSX, scaled by a transform, and relies on CSS for stroke properties and line joins. No external libraries are used; it is a pure React rendering of SVG primitives.
