SVG Polygon

SVG Polygon – <polygon>

The <polygon> element is used to create a graphic that contains at least three sides.

Polygons are made of straight lines, and the shape is “closed” (all the lines connect up).

Polygon comes from Greek. “Poly” means “many” and “gon” means “angle”.

Example 1

The following example creates a polygon with three sides:


Here is the SVG code:

Example

<svg height="210" width="500">
  <polygon points="200,10 250,190 160,210" style="fill:lime;stroke:purple;stroke-width:1" />
</svg>

Code explanation:

  • The points attribute defines the x and y coordinates for each corner of the polygon

Example 2

The following example creates a polygon with four sides:


Here is the SVG code:

Example

<svg height="250" width="500">
  <polygon points="220,10 300,210 170,250 123,234" style="fill:lime;stroke:purple;stroke-width:1" />
</svg>


Example 3

Use the <polygon> element to create a star:


Here is the SVG code:

Example

<svg height="210" width="500">
  <polygon points="100,10 40,198 190,78 10,78 160,198"
  style="fill:lime;stroke:purple;stroke-width:5;fill-rule:nonzero;" />
</svg>


Example 4

Change the fill-rule property to “evenodd”:


Here is the SVG code:

Example

<svg height="210" width="500">
  <polygon points="100,10 40,198 190,78 10,78 160,198"
  style="fill:lime;stroke:purple;stroke-width:5;fill-rule:evenodd;" />
</svg>
