This visualization demonstrates basic SVG shape primitives—a green circle, two thin blue rectangles, a black line, and a blue polyline path—drawn directly in an HTML page. The code uses raw SVG elements with coordinates and stroke properties, including a path with a `d` attribute defining line segments. No external libraries are employed; the rendering relies solely on the browser’s built-in SVG support. The layout shows shapes positioned independently across a 500-pixel-tall canvas, with overlapping strokes and varying fill styles to illustrate core vector graphics capabilities.
