<polyline> - SVG: Scalable Vector Graphics 编辑

The <polyline> SVG element is an SVG basic shape that creates straight lines connecting several points. Typically a polyline is used to create open shapes as the last point doesn't have to be connected to the first point. For closed shapes see the <polygon> element.

<svg viewBox="0 0 200 100" xmlns="http://www.w3.org/2000/svg">
  <!-- Example of a polyline with the default fill -->
  <polyline points="0,100 50,25 50,75 100,0" />

  <!-- Example of the same polyline shape with stroke and no fill -->
  <polyline points="100,100 150,25 150,75 200,0"
            fill="none" stroke="black" />
