This example illustrates fundamental SVG concepts through a single interactive graphic, covering shape stacking order, styled line elements, various path types including quadratic and Bézier curves, polygon shapes, and the use of `<g>` groups for organization. It demonstrates how shapes render in document order and how different stroke and fill options affect appearance. The visualization is built entirely with raw SVG markup, using elements like `<circle>`, `<line>`, `<path>`, and `<polygon>` within a structured layout, rendered directly in the browser without any external libraries.
