With this primitive library you can do things like this:
from ascii_canvas import canvas
from ascii_canvas import item
canvas_ = canvas.Canvas()
rect_a = item.Item('+-----+\n|Hello|\n+-----+', position=[0, 0])
rect_b = item.Item('+-----+\n|World|\n+-----+', position=[16, 5])
rect_c = item.Item('+-+\n|!|\n+-+', position=[32, 0])
line_a = item.Line(start=[7, 1], end=[15, 6])
line_b = item.Line(start=[23, 6], end=[31, 1])
canvas_.add_item(rect_a)
canvas_.add_item(rect_b)
canvas_.add_item(rect_c)
canvas_.add_item(line_a)
canvas_.add_item(line_b)
print(canvas_.render())
Which results in this output:
+-----+ +-+
|Hello|----+ +----|!|
+-----+ | | +-+
| |
| |
| +-----+ |
+----|World|----+
+-----+
