1. Data Visualization
Hook
Data are just numbers.
They give us nothing
without processing.
Key details
Data visualization is the representation of
data in the form of graphs and tables. Data
are just numbers, but visualization makes
them more understandable.
Goals of data visualization:
•The meaning of the data displayed is easy to
understand for everyone.
•Obtain new information and knowledge.
More details
Actual data visualization steps
(1) Collect data.
(2) Extract only the data you want to use from the
collected data and create a data set.
(3) Write a program that reads the data set created
in (2) and displays it as a graph.
I actually visualized my lab's slack (communication
tool) data. This time I visualized how much and what
time members post to slack.
From this graph, we can see that the
person posted actively from about 10:00
am to 10:00pm. In this way, we can obtain
new information that we have not been
able to see before by visualizing the data.
