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.
Regards,
Daniel
