DATA VISUALIZATION

WHY IS DATA VISUALIZATION
IMPORTANT?

Big data is a broad term for data sets so large or complex that
traditional data processing applications are inadequate. Challenges
include analysis, capture, curation, search, sharing, storage,
transfer, visualization, and information privacy.
Big data is distinct from the internet, although the web makes it
much easier to collect and share data.

WHAT IS DATA
VISUALIZATION?

One of the most important benefits of visualization is that it
allows us visual access to huge amounts of data in easily
digestible visuals.
Well designed data graphics are usually the simplest and
at the same time, the most powerful.

Possible Process
Research, design, & development
teams come in here, processing
information and building a user
friendly tool. This is the
visualization phase.
Data mining, understanding a
potential strategy and story.
This is the discovery phase.
A web experience is created giving
the user a data-driven experience.
This is the experience phase.

WHAT MAKES
GOOD DATA VIZ?

Everything depends on the concept of layering, establishing
hierarchies and making them clear.
Challenging the viewer to think about the substance rather than
about the methodology, graphic design, or the technology used
to make the visualization.
Encourage the eye to compare, reveal the data at several levels
of detail, from a broad overview to minute statistics.

STORYTELLING

Data analysis are the stories we desire to tell. Visual composition is
the main architecture and the aesthetic value we desire to present.
Storytelling with data visualization creates an impactful response
from the user with numbers to back it up.
Data visualization plays a critical role in modern journalism.

DATA VISUALIZATION
VS. INFOGRAPHIC

Data visualization (data graphics) help you understand trends,
patterns, and to make correlations. They’re typically instruments
for reasoning about quantitative information.
Information graphics (info graphics) are typically a representation of
not only specific data points but information as well. They’re
usually instruments for reasoning about qualitative information.

Information graphics are visual representations of information, data
or knowledge often used to support information and strengthen it.
Data visualizations are visual displays of measured quantities by
means of the combined use of a coordination system, points, lines,
shapes, digits, letters quantified by visual attributes.
Both can be static, animated or interactive.
