A single, continuous polyline forms a zigzag pattern across the SVG viewport, alternating between the top and bottom edges. The line, defined by a single `polyline` element, uses coordinates that increment horizontally by roughly 9.7 units, creating a regular sawtooth wave. The rendering relies on raw SVG, with the polyline’s points explicitly listed in the markup. The visualization demonstrates a minimal, purely geometric data trace, showing how a sequence of values can be encoded as alternating high and low positions. No external libraries are used; the example relies on the native SVG polyline API.
