## Configuration Options for PolygonSymbolizer
[[Symbolizer|SymbologySupport]] that specifies rendering of an area enclosed by a polygon.
A PolygonSymbolizer is often used to render the area enclosed by a [polygon](http://en.wikipedia.org/wiki/Polygon). For example, the `rundemo.py` and `rundemo.cpp` applications use PolygonSymbolizer objects to "fill-in" [Canadian provinces with different colors and to make bodies of water look blue](https://raw.githubusercontent.com/wiki/mapnik/mapnik/images/demo256.png).
