This document discusses the importance and benefits of data visualization. It notes that data visualization is the process of transforming numbers into graphs or images to reveal new insights and patterns in the data. It explains that visualizing data makes it easier to understand than raw numbers, allows people to see underlying patterns and insights, and gives a fuller picture than any single dataset alone by allowing comparison of relative data. The document advocates that managers should recognize the value of visualizing data to better analyze and make decisions based on the insights it provides.

3. Data Visualization
Data visualization is the art of transforming
a set of numbers in to graphs and images
in a way that can reveal new insights and
underlying patterns in the data. 3

The greatest value of a picture
is when it forces us to notice
what we never expected to see.

6. Why Visualize Data
▹ Numbers are hard to understand
▹ Pictures and graphs are easier to understand
and interpret
▹ Gives us new insight
▹ Reveals underlying patterns that would not
have been possible to see without data
visualization

7. DATA IS THE NEW

8. Eye is sensitive to
patterns is
variations in colour,
shape, size
TWO KEY INSIGHTS
Relative data can
give us fuller
pictures. It can
lead to change
our perspective
in the right
direction.

9. Analyzing using our eye

We can understand data better when we
see a graphic representation of the data
instead of the numbers. The eye is
sensitive to variations in colour, shape,
patterns; all these gives us unconscious
insight into the data. The language of the
eye and the language of the brain; which
is numbers and concepts; together
combined gives deep meaningful insight
into the data.

10. Relative Datasets
10
● No one set of data can give us the full
picture.
● It can often lead us into the wrong
direction
● Comparing two similar data sets can
lead us to the fuller picture.
● Relative data can give us the right
insight

11. HOW CAN
MANAGERS USE
THIS INSIGHT?

12. Visualizations
▹ Managers should realize the importance of data
visualizations.
▹ Data visualizations can make it easier to
analyze the data
▹ Managers should spend time and resources to
visualize data in a creative way.

13. The Full Picture
▹ People might be mislead if they only
analyze only a particular data
▹ Other data sets must be analysed
also
▹ Relative data can reveal the bigger
picture
▹ Managers can make the proper
decision when they have the full
picture

14. Closing Off
Visualizing data in an elegant way is often times hard
and frustrating. It takes time and resources to scrap the
data from the internet, clean the data, organize the data
and then plot it on a graph. This takes considerable time
and effort. But this as enormous benefits and lead to
deeper insights that were previously not available. So
every company should invest in data visualizations!!
