Hi,
I am kind of stuck how to draw rectangle line based on bbox value (lower
bottom and upper corner).
There are LineSymbolizer but seems like it does not base on drawing line
between to point.
There are some example from this forum that use LineSymbolizer in Python but
the line represent the shape
not drawing line between two point.
Thank you in advance,
John

lower_left_xy = p.forward(Coord(-180.0, -45.0))

bbox = Envelope(lower_left_xy,upper_right_xy)
m.zoom_to_box(bbox)
