In addition to the above attributes, it provides the following methods.

add_arrow TIP, TAIL=None, ARROW=arrow.default | Function

This method adds a straight arrow that points to TIPLOC, which is a tuple of integers. TAIL specifies the starting point of the arrow. It is either None or a string consisting of the following letters: 'l', 'c', 'r', 't', 'm,', and 'b'. Letters 'l', 'c', or 'r' means to start the arrow from the left, center, or right of the text box, respectively. Letters 't', 'm', or 'b' means to start the arrow from the top, middle or bottom of the text box. For example, when `tail = 'tc'` then arrow is drawn from top-center point of the text box. ARROW specifies the style of the arrow. See arrow.
