I found an example for both good and bad graphics that explain airplane safety. The first is a demonstration of good graphics. The reading order is very comprehensible as it is left to right and then top to bottom for each set of directions. The drawings clearly indicate important steps in the procedures by dividing steps into frames, zooming in at some parts, as well as picturing what not to do for comparison. The style is of cartoon quality but all proportions are accurate to compare to real life and make you take it more seriously.
Bad graphics
The second picture of airplane safety is an example of poor quality of graphics. All procedures are indicated according to one drawn picture, so it is very jumbled and it makes you want to read all the steps at once. Many aspects of the safety related to the chair are not explained well and someone may not know how to use them correctly. Also, it is strange and inconsistent that the seat belt is explained in opposite diagonals of the picture. The fact that there are a bunch of arrows going all over the chair also makes your eye go around everywhere and does not have a good order of reading. Also it is weird that they use two different styles of graphics between the chair and the "take off and landing" and the "no smoking".
