This example displays a set of basic SVG shapes—two circles and two rectangles—positioned on a 960×500 canvas. It demonstrates how to define shapes and apply fill colors using SVG attributes. The first circle and rectangle rely on default black fill, while the second pair use explicit red and green hex values. The page is styled with CSS, setting a monospace font and hiding overflow, while the shapes are rendered directly inline in HTML without any JavaScript libraries or data sources.
