This example demonstrates fundamental SVG shapes—a red circle, a blue-stroked light blue rectangle, and a light green triangle—arranged on a 960-by-500 canvas. It functions as a static, hand-coded HTML document using raw SVG elements (`circle`, `rect`, `path`) without external libraries. The path uses the `d` attribute with absolute coordinates (`M`, `L`, `z`) to draw the triangle, and each shape directly specifies its fill, stroke, and stroke-width attributes, showcasing basic vector rendering principles.
