This example demonstrates basic SVG shape rendering with a circle, a red line, and a black path. The shapes are drawn directly in the HTML markup using inline SVG elements within a 960x500 viewport. The code uses no JavaScript libraries, relying solely on native SVG attributes like `cx`, `cy`, `r`, and `d` for positioning and geometry. Static styling such as stroke color and width are applied via element attributes, while a separate stylesheet defines a class rule that is not currently used by any visible element.
