This example demonstrates the fundamental building blocks of SVG shapes in a static 960x800 canvas, using plain SVG markup directly in the HTML. It shows three circles with different radii and colors, a yellow rectangle with a navy stroke, a red diagonal line, and a black polyline path defined by an M/L command sequence. The rendering relies on native SVG elements such as circle, rect, line, and path, with attributes like cx/cy, width/height, and stroke-width. No JavaScript or external libraries are involved, highlighting core SVG syntax for geometry and styling.
