Detailed Description

Draws a line between two points, one or both of which is in
global coordinates.

Line(x1, y1, x2, y2, lcoal1, local2, arrow_start, arrow_end, attribute=value)

x1, y1                  required        the starting point
x2, y2                  required        the ending point
local1                  default=False   if True, interpret first point as a
                                        local coordinate (apply transform)
local2                  default=False   if True, interpret second point as a
                                        local coordinate (apply transform)
arrow_start             default=None    if an identifier string/Unicode,
                                        draw a new arrow object at the
                                        beginning of the line; if a marker,
                                        draw that marker instead
arrow_end               default=None    same for the end of the line
attribute=value pairs   keyword list    SVG attributes
