Poor Graphic

State of the Planet - Bigger, Faster, Stronger, More

Arguments why it is a poor graphic

• Principles of Graphical Integrity

• lie factor:the right graphic seems to be much larger then the left. it should be only 1,5 times larger then the other one based on the data. The size of the effect in data is 5,7% and the effect in the graphik about 1,55%, which results a high lie factor of 2,97.(BIN MIR NICHT SICHER) Its lie factor should have a value between 0.95 and 1.05.
• the numbers are not readable and the lines between the numbers are not needed and very irritating.
• a pseudo 3-dimensional graphic is used to show 1-dimensional data

• data-ink ratio:very poor data-ink ratio.
• visual clutter:
• Data Density:
• Chartjunk:
• in the text a reason for increased hurricans is mentioned, but in the shown data is no evidence for that, because there is no reason related data.
