This example demonstrates fundamental Scalable Vector Graphics (SVG) shapes rendered directly within an HTML document. It shows a pink circle, a yellow rectangle with a navy border, a black diagonal line, and a red polyline path composed of relative line commands. The visualization relies on the native SVG element namespace inside an HTML file, using attributes like `cx`, `cy`, `r`, `x`, `y`, `width`, `height`, and the `d` path data syntax to define each shape's geometry and styling without any external libraries.
