This example demonstrates fundamental SVG rendering primitives by combining overlapping circles, lines, and custom paths on a 960 by 500 canvas. The graphic pairs a small green circle inside a larger red one to illustrate fill and layering, then shows a thick navy stroke along a coordinate path and a black open path with explicit line segments. The operations run directly through the `svg` element in an HTML document, using inline `circle`, `line`, and `path` tags. The drawing relies entirely on static SVG markup, with no scripting or external libraries, and reflects a simple exercise in vector graphics construction.
