Hi All!
Challenge: You want to display three circles with diameters 1.0, 1.5 and 2.0. Using Bubble (2D) we get the following picture:
. Obviously, QM by default draws circles so that their areas are related as squares of diameters, which is true mathematically, but incorrect financially and economically.
Here’s how this problem looks, eg, in Tahir’ video on his YouTube channel:
. You see, the sales of the USA and Germany differ twice. But the areas is four times.
Q1: is it possible to force QM to draw circles so that their areas are visually perceived as relations of given diameters?

Q2: Is it possible to force QM to display labels with a vertical offset? – My answer to Q2. Yes, its possible.
Here’s how my solution works:
