A polyline is a shape consisting of a set of sequentially connected vertices. The polyline can have self-intersections.
The polyline can be created in two ways: using the GeoObject
class with the "Polyline" geometry type,
or using the Polyline auxiliary class.
When creating a polyline, you can set properties
(such as the contents of a balloon or hint) and
options (such as color and line width).
Polylines, like other geo objects, can be combined in collections.
