Hi Bunuel,
From the
OG statements below regarding DS, how do we derive that figures are
not drawn to scale?
Bullet 1 says "figures conform to the information given in the question". The question says "of the four numbers
represented on the number line above" -> the word
"represented" confuses me here
Bullet 3 says "The positions of points, angles, regions, etc., exist in the order shown, and angle measures are greater than zero" -> You could use this bullet to argue that the number line in this prompt is therefore not drawn to scale, however the bullet also doesn't say it is NOT drawn to scale.
Generally speaking I'm looking for some clear rules regarding pictures in DS questions. For PS it is crystal clear: drawn to scale unless stated otherwise. What's the general rule for DS? Would it be safe to assume: NOT drawn to scale unless stated otherwise?
Thanks for the clarifications

No, you absolutely cannot assume that.
OFFICIAL GUIDE:Problem SolvingFigures: All figures accompanying problem solving questions are intended to provide information useful in solving the problems. Figures are drawn as accurately as possible. Exceptions will be clearly noted. Lines shown as straight are straight, and lines that appear jagged are also straight. The positions of points, angles, regions, etc., exist in the order shown, and angle measures are greater than zero. All figures lie in a plane unless otherwise indicated.
Data Sufficiency:Figures:• Figures conform to the information given in the question, but will not necessarily conform to the additional information given in statements (1) and (2).
• Lines shown as straight are straight, and lines that appear jagged are also straight.
• The positions of points, angles, regions, etc., exist in the order shown, and angle measures are greater than zero.
• All figures lie in a plane unless otherwise indicated.
