The points attribute defines a list of points. Each point is defined by a pair of number representing a X and a Y coordinate in the user coordinate system. If the attribute contains an odd number of coordinates, the last one will be ignored.

Two elements are using this attribute: <polyline>, and <polygon>

<svg viewBox="-10 -10 220 120" xmlns="http://www.w3.org/2000/svg">
<!-- polyline is an open shape -->
<polyline stroke="black" fill="none"
points="50,0 21,90 98,35 2,35 79,90"/>

<!-- polygon is a closed shape -->
<polygon stroke="black" fill="none" transform="translate(100,0)"
points="50,0 21,90 98,35 2,35 79,90"/>

<!--
It is usualy considered best practices to separate a X and Y
coordinate with a comma and a group of coordinates by a space.
It makes things more readable for human beings.

polyline

For <polyline>, points defines a list of points, each representing a vertex of the line to be drawn. Each point is define by a X and Y coordinate in the user coordinate system.

Note: A polyline is an open shape, meaning the last point is not connected to the first point.

Value [ + ]# none Yes

Example

<svg viewBox="-10 -10 120 120" xmlns="http://www.w3.org/2000/svg">
<!-- polyline is an open shape -->
<polyline stroke="black" fill="none"
points="50,0 21,90 98,35 2,35 79,90"/>
</svg>

polygon

For <polygon>, points defines a list of points, each representing a vertex of the shape to be drawn. Each point is define by a X and Y coordinate in the user coordinate system.

Note: A polygon is a closed shape, meaning the last point is connected to the first point.

Value [ + ]# none Yes

Example

<svg viewBox="-10 -10 120 120" xmlns="http://www.w3.org/2000/svg">
<!-- polygon is an closed shape -->
<polygon stroke="black" fill="none"
points="50,0 21,90 98,35 2,35 79,90" />
