Shubham, The "first input point" part sounds good.
Then we need a list. You could look at the sketch or pipe how they are doing it. We can have multiple texts and lines in any order here. Regarding the text position, I would use flags, e.g. "bl" or "cc" which means [t]op, [b]ottom, [l]eft, [r]ight, [c]enter. (What is "none"?) Keep in mind that this is the basic command to create any annotation. There may be additional convenience functions as (a hypothetical) "annotate <region> <text>" which creates a line with predefined length and angle from the center of the region and puts the text at the end of it. But first, you have to create the foundation: The basic annotation primitive with its command line interface.
