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.
The option VertexColors->{c1, c2, ...} can be used to specify that the color of the line should interpolate between colors ci specified for each point.
In 3D, the option VertexNormals->{n1, n2, ...} can be used to specify effective normals at each point, to be interpolated for purposes of smooth shading.
Joining of line segments can be specified using JoinForm.
