The fork demonstrates basic SVG shape construction inside a plain `index.html` file, using the SVG element itself without any external libraries. It renders two overlapping circles to show layering and opacity effects, a straight line segment, and two paths with explicit coordinate data to illustrate line drawing and path commands. The code is primarily a static, hand-authored SVG canvas, with one path containing a complex cubic Bézier curve sequence and another tracing a simple polylined route.
