This example demonstrates fundamental SVG shape elements, including circles and rectangles, with various fill colors and stroke styles. A path element draws a polyline connecting three points, while a commented-out line element shows an alternative shape. The SVG canvas is defined directly in the HTML with a width of 960 and height of 500, using no external libraries. Shapes are positioned using x, y, and r coordinates and attributes like fill, stroke, and stroke-width, showcasing basic vector graphics rendering in the browser.
