This example demonstrates a set of basic SVG shapes rendered directly within an HTML document, including circles, rectangles, a line, and an ellipse. It showcases core SVG styling attributes such as fill colors, stroke width, and stroke color applied to each element. The visualization is created using raw SVG markup without any external libraries, presenting a static composition of geometric primitives on a 500 by 500 pixel canvas. The code relies on the native SVG coordinate system, defining positions and dimensions via attributes like `cx`, `cy`, `r`, `x`, `y`, `width`, and `height`.
