This example demonstrates how SVG shapes and CSS classes define reusable graphics with varied colors, strokes, and transforms. It shows circles, rectangles, straight lines, and curved paths arranged in a scaled group, with styling applied through class selectors. The code relies on raw SVG elements like `<circle>`, `<rect>`, `<line>`, and `<path>`, using `<defs>` and `<use>` for reuse, plus CSS rules for fill and stroke properties. A hidden SVG defines the symbols, while the visible viewport renders them at a scale of 1.7.
