A demonstration of SVG shape fundamentals, this example draws a collection of primitive graphics directly onto an SVG canvas within an HTML document. The code displays three circles with varying radii and fill colors, a large yellow rectangle with a thick blue stroke, a green diagonal line, and a filled orange path. The path defines a triangle using absolute movement (M) and line-to (L) commands, showing how paths connect multiple points. The example illustrates the syntax for specifying center coordinates (cx, cy) for circles, the upper-left corner positioning for rectangles, and the layering of SVG elements.
