This integrated reasoning graphics interpretation question involves bubble charts. Some of you may not be familiar with bubble charts, but they're essentially just like regular 2-dimensional charts, but they add a 3rd dimension. The size of the bubble is the 3rd dimension. Sometimes the size of the bubbles are not labeled - in which case the only the relative size of the bubbles is important.
In other cases, like the one above, the bubble chart will actually give a numeric value to the size of each bubble.
Sometimes bubble charts can even introduce a color component as the one above includes. The color component is more used as a measure of qualitative differentation - rather than quantitative differentation. For example, there would be no way to plot the numerical value of the prestige level - unless there were some system that assigned a numerical value to the prestige level. In this case, the colors orange, blue, and green are simply used as a way to differentiate the level of prestige.
What This Bubble Chart Can Tell Us:
1) The bombordier is the most expensive private jet of the 5 shown - priced at $3.2M. It also requires the fewest number of feet to takeoff and is also at the oragen prestige level.
2) The cheapest private jet is the Gulfstream Mini - priced at $1.4M. It also gives the fewest inches of leg room and is in the 3rd tier in terms of prestige.
