What is the difference between a ring and a polygon in forcing geometry?
I am confused about ring and polygon in Boost.Geometry.
There are no pictures in the documentation showing what a ring is and what a polygon is.
Can anyone draw a shape explaining the difference between the two?

In Boost.Geometry, a Polygon is defined as an areal geometry containing an outer ring and a number of inner rings (holes).
The ring represents one of the polygons. It differs from OGC LinearRing because it represents geometry. When used alone, it can be viewed as a polygon with no holes.
