What it is and Why it is important?
Data visualization is the presentation of data in a pictorial or
graphical format. For centuries, people have depended on
visual representations such as charts and maps to understand
information more easily and quickly.
Because of the way the human brain processes information, it
is faster for people to grasp the meaning of many data points
when they are displayed in charts and graphs rather than
poring over piles of spreadsheets or reading pages and pages
of reports.
Why?
Visualizations help people see things that were not obvious to
them before.
Even when data volumes are very large, patterns can be
spotted quickly and easily.

Blue fields are discrete – they contain a FINITE
number of values – for example – the field
REGION may contain the values
North/South/East & West, but no others
Green fields are continuous – they could contain
an infinite number of values – for example the
PRICE of an item could be any value along a
number line.
