Textual visualization involves mapping words and looking at
their pattern in a visual perspective.
This makes you look at maps in a completely different way. For example, this map is surrounded on the view of chemistry and the popularity of the departments located within. The popularity is dictated by the colorful circles that become larger or smaller due to the number of students who graduated successfully with Phd's in their respective programs.

Pie Chart
A pie chart is a circular graph that is divided into sectors
in order to display numerical proportion. The name itself comes from its
resemblance to an actual pie. Pie charts are very common and used in a variety
ways to show things such as measuring education, political factors, economic
impacts, and etc. The pie chart above shows a pie chart of countries in comparison to population size.
Bathymetric Maps
Bathymetric maps look at sea floor elevation. It is
essentially the underwater counterpart of an above water topographic map. It serves to measure the depths of
water. The map above is showing the gulf of Maine and looking at the depths of water throughout the area as measured through meters. It also uses false colors in order to display deeper bodies of water in comparison to more shallow areas.
Geopotential Height Map
Geopotential height maps is the elevation of a given air
pressure. It approximates the true height of a pressure surface above a mean
sea level. An example of geospatial height is when cold air is less dense than
warm air; the pressure surfaces then tends to rise. This shows that heights are greater
in warm air pockets.
Albers Equal Area Projection
Albers Equal Area Projections are used for maps showing
specifically the United States, or large areas within its borders. This conic
projection is also used for other large countries as well. The Albers Equal
Area Projections have equal area and are excellent for thematic maps because it
keeps the states at the same size. This can be used to display population
distributed across a state or regions area.
Mercator Projection
One of the most common map projections is the Mercator
projection. The Mercator projection is a conformal map; this means it projects
true shapes. The simple outline of the 7
continents corresponds very closely to what is seen in the real world. The
Mercator world map was made in 1569 and is one of the most popular maps known to date.
Cartographic Animation
Cartographic animation is the use of animation
through videos or computers in order to add a time-based factor to a map. This
displays change in some dimension that is typically displayed as an “over time”
effect. The animation is typically shown at a much faster, or slower rate, to
show the viewer the desired effect. Cartographic animation is used to show the
effects of things such as tsunamis, thunderstorms, and hurricanes to show how
the component spreads across the region.
Mental Map
A mental map looks a person’s perception of an
area of interaction. Mental maps can show things such as how a person perceives
geography through things such as geography as well as what their personal
preferences are.
