Businesses Reporting, Visual Analytics and Dashboards (part 2) and Story Telling
Pre-Attentive Attributes
Color
Form
Position
Motion
Gestalt Principles of Visual Perception
Principle of Proximity
objects that are located
near one another
belongs together
Principle of Closure
open
structures that are viewed as
closed, compete or regular
not necessary
as it creates clutter
Principle of Similarity
objects that
share some visual attributes
belong together
Principle of Continuity
objects that are
aligned with one another
belongs together
Principle of Enclosure
objects enclosed by
a visible border
belongs together
Principle of Connection
objects that are being
connected in some way
belongs together
stronger than
being grouped by proximity or similarity
Dashboard Design Considerations
Reduce the non-data pixels
Eliminate all unnecessary non-data pixels
graphics with
only decoration
variations in colour
that don't encode any meaning
unnecessary
borders
complete borders
when a single set of axes would adequately define the space
unnecessary fill colours
to separate sections of display
gradients of fill colour
on bars and background
unuseful
grid lines
3D displays
that does not represent actual data
De-emphasize and regularize the non-data pixels that remain
axis lines and gridlines should be
muted
navigational controls
should not take up more space
than visual displays
instructions
display on a
separate screen
display on a
pop-up menu
Enhance the data pixels
Eliminate all unnecessary data pixels
removing
less relevant data
condensing data through
summaries and exceptions
multi-foci displays
(more details on recent data, less for distant data)
important
information can be emphasized using
static means
important
information requires a
dynamic means of emphasis
Highlight the most important data pixels that remain
layout of dashboard
should not change
dynamically
different regions = different degrees of
visual emphasis
Organize Information to Support its Meaning and Use
according to business functions, entities and use
co-locate items that are in the same group
delineate groups using least visible means
use of
white space
use of
subtle
borders
support meaningful comparisions
combining items in
a single table or graph
placing items
close together
linking items using a
common colour
use of comparative values (ratio, percentage)
maintain consistency
differences
in appearance prompts us to search for those differences
consistency in
visual appearance
and
choice of display media
select the medium that
best communicates data
and its
message
make view experience aesthetically pleasing
design for use as a launch pad and testing
for
additional, complementary
information
dashboard interaction (able to drill down)
principles of incorporating interaction
viewers can initiate the launch by
clicking the data itself
hover over data
and the value
pops up as a text
use
consistent launch actions
to avoid confusion
test design for usability
present a
single prototype
of the
most effective design
created
show a prototype populated with
real data
discourage meaningless comparisons
Telling a Story from your Data
Purpose?
make sense
and
order
of data
see the
whole
where there are disparate parts
giving vision to what the future
can look like
interactive
supports an
arguement
What makes a good story?
involves
characters
challenges
is believable
hurdles
to overcome
outcome is
clear
5 steps to creating a good story
Think of your analysis as a story
explore the data
determine
what you want people to do
as a result
write out the
"story board"
for audience
Be authentic
make it
personal/emotional
start with
metaphor
or
anecdote
use
facts
Be visual
use
graphs, charts, pictures
use
descriptive titles and captivating images
design graphs that are
instantly readable
include
subject's theme
into the design and display itself
Make it easy for your audience and you
simple and direct
story telling
stick to
2 to 3 key issues
and how they
relate to audience
Invite and direct discussion
highlighting what the
audience needs
highlight
relatable key facts
extend story parameters into
questions
continue discussion via
group discussion, blogs, intranets
