Building Data Sets to
Support Visualization
This chapter focuses on the building of data sets and storing them in formats
conducive to data access and creating great visualizations. We will cover a
number of common and more unique data sets and discuss specifically the
uses, types of data, creators and consumers, and benefits or drawbacks to
each data source.
wHAT DATA SeTS ARe
Data sets
are groups of information that may be stored in a number of formats
in today's digital age. These formats can include lists of customers, products,
sales records, or even logs from a server or computer system. These sets are
then combined in a number of different ways to produce information that
businesses can use to drive decisions.
WHy WE NEED THEM
We need these data sets to help us answer questions such as these:
uu
What are our customers buying?
uu
What products are the most profitable?
uu
What kinds of trends do we see in our sales over time?
uu
How do these trends affect the buying behavior or volume of sales?
