In such error cases the user agent will drop the last, odd coordinate and otherwise render the shape. — https://w3c.github.io/svgwg/svg2-draft/shapes.html#PolylineElementPointsAttribute This is a square. <svg width="100px" height="100px" viewBox="0 0 300 300"> <desc>polyline odd number of points coordinates</desc> <polyline fill="none" stroke="blue" stroke-width="5" points="50,150 150,150 150,50 50,50 50,150 " /> </svg> 5 points / missing last y coordinates.
