Detailed Description

Draws a line between two points.

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

x1, y1                  required        the starting point
x2, y2                  required        the ending point
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
