This example demonstrates the visual contrast between filled and stroked SVG shapes—a rectangle, circle, and triangulated path each appear twice, once with solid fill and once with a white fill and black stroke. The rendering uses raw SVG elements (`<rect>`, `<circle>`, `<path>`) within an inline `<svg>` tag, with a white background rectangle. No JavaScript libraries are employed; the geometry is defined statically in the markup, and the path coordinates are hardcoded. The piece shows how fill and stroke alter the perception of identical forms.
