Poor Graphic
Arguments why it is a poor graphic
Principles of Graphical Integrity
- Lie Factor: The right graphic seems do 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 graphic 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.
- A large share of ink is used to show the pseudo 3-dimensional graphic.
- The ink don't change as the data change.
- 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.
