A single SVG path demonstrates an arc segment, drawn from point (0,50) to (50,0) with a 50-pixel radius using the `M` and `A` path commands. The canvas is a fixed 960×500 SVG element with the `body` margin zeroed for full-browser display. The code uses no JavaScript libraries, relying solely on native SVG path syntax and the `fill="none"` and `stroke="black"` attributes to render the curve. The example illustrates fundamental vector shape construction without external data.
