significance of visualization
Cave Drawings and Early Language
Development

Primitive man in ancient cultures left behind
cave paintings and hieroglyphs. To save space
and time, pictures gradually became stylized
and ultimately evolved into characters.
Cave Drawings and Early Language
Development

As societies became more complex so did
languages; and as travel brought people of
different cultures together, written languages
evolved further to be more versatile.
Hundreds of characters could be narrowed
down to a select set of "letters." An entire
language could then be represented using
various combinations of letters.
Perspective Drawings


Through observation,
artists sought methods to
portray images of the
world around them.
During the time of the
Renaissance, perspective
(space and depth
relationships) became a
very important part of the
desire to produce realistic
images.
Maps




A map is a flat representation
of a 3D space.
The item can be as large as our solar
system or earth, or as small as
chromosomal genes.
Maps show our world as a set of points,
lines, and areas, using many different
features, such as size, shape, value,
texture, pattern, color, and orientation.
The kind of map you use depends on the
kind of information you want to obtain or
analyze.
Different kinds of Maps


Road Maps – Show
roadways and physical
boundaries.
Topographic Maps –
Have contour lines
that show elevation.
Different kinds of Maps


Aeronautical Maps –
Have information
about flight paths.
Weather Maps – Show
locations of weather
patterns.
Different kinds of Maps

Concept Maps – There
are several kinds of
concept maps. A
spider map is
organized by placing
the central theme or
unifying factor in the
center of the map.
Outwardly radiating
sub-themes
surrounding the
center of the map.
Different kinds of Maps

The hierarchy concept
map presents
information in a
descending order of
importance. The most
important information
is placed on the top.
The flowchart concept
map organizes
information in a
linear format.
Different kinds of Maps


Gene Map –Shows locations of specific
genes in DNA
Floor Plan – Shows rooms in a building.
Photography


The development of
photography depended on
understanding the physics of
light to record images and
chemical processes to produce
permanent images.
The improvement of materials
(celluloid film) and processes
allowed everyone to enjoy the
photographic process. This
process allowed the pictures to
be recorded on an easy to use
medium.
Television


With the invention of
television, images could
be brought into the home.
Television combined
sound with motion and
eventually color was
added.
