Line[, , ... ] is a graphics primitive which represents a line joining a sequence of points.
Line can be used in both Graphics and Graphics3D (two- and three-dimensional graphics).
The positions of points can be specified either in ordinary coordinates, as x, y or x, y, z, or in scaled coordinates as Scaled[x, y] or Scaled[x, y, z].
Offset can be used to specify coordinates in two dimensions.
The line consists of a sequence of straight segments joining the specified points.
Line thickness can be specified using Thickness or AbsoluteThickness.
Line dashing can be specified using Dashing or AbsoluteDashing.
Line shading or coloring can be specified using CMYKColor, GrayLevel, Hue or RGBColor.
