 Will data visualization help us make better decisions? Justify your response:
1. It contributes to discovering a pattern of possible future scenarios to justify
an action, or to adapt quickly to a tendency
2. Data graphics is easy to read then it helps to change the perspective of a
problem
3. The figures of data visualization can also be connected to other figures to
make a bigger picture of a situation
4. It squeezes large amounts of data into small presentations easy to
understand
5. Data visualization provides a new elegant and quick solution to solve
problems
6. Excellent tool for perception of a problem with statistical numbers

4. CEN4722 – Assignment 6
 What are the downsides? Please list below:
1. To create those graphics valuable data could be excluded, and other not
relevant included to preserve the visualization
2. Data visualization does not draw conclusions
3. Data visualization does not show causes
4. The conclusions based on data visualization are based on preconceived
ideas of size, and proportions that the original data collector used to
prove its point
5. Same as statistics, data can be manipulated, and graphics could mislead
in a wrong context, even with no bad intention
6. Due to the nature of the graphic presentation and the exclusion of raw
data people perceives the information given in the same way. No
discrepancy is possible.
