Dasymetric Map
Dasymetric map is a thematic map used to classify volumetric data. This map is used often for population density since it has the ability of realistically place data.
Cartogram
This above cartogram shows each county in the United States rescaled according to population. The map is distorted to convoy the information in an alternate variable.
Dopplar Radar
A Doppler radar is able to show the path of a storm and type of precipitation. It can estimate two parameters, reflectivity and rotational velocity.
Cartographic Animations
Cartographic animations are able to show changes in data in a continues fashion.
Hypsometric Map
Hypsometric maps are used to show differences in elevations in maps and different colors are used to display the differences.
Isohyet
An isohyet uses contour lines to represent the amount of rainfall on a map. Each color in the above map shows the different amount of perception month to data for that location.
Isobars
Isobar maps are used to display atmospheric pressure over an area.
Isopach
This is an isopach map of Oatka Creek Shale and limestone thickness. The map is measured in feet. This site used many different maps to represent information. An isopach map uses contour lines of equal thickness over an area.
Isopleths
Isopleths generalized and simplifies data with continuous distribution. They are more commonly used to map areas containing elevations, amounts of precipitation, and numerous other measurements. The lines connect points of equal values.
DRG
DRG or digital raster graphic is a scanned image of a standard series topographical map. On average these maps contain 250 dots per inch. These maps are standard for the U.S. Geological Survey.
Standardized Choropleth Maps
A standardized choropleth maps has data that has been standardized to allow for easier comparison of data in different areas.
Bivariate Choropleth Map
Bivariate choropleth maps display two forms of information on a single map. Different colors are used to portray the two types of information at the same time. They have the ability to display how information or variables can relate to each other.
Portolan Chart
This portolan map depicts the Mediterranean, the Black Sea, the Sea of Azov and the Atlantic coasts of Europe and North Africa. This is another example of cartography from the medieval era.
T-O Map
A T-O map is an medieval world map and is one of the earliest known maps of its type. It is a representation of the physical known world at that time.
Statistical Map
This is an example of a statistical map. It is a very simple map displaying the number of people that can be found online in northern Africa and the Middle East.

Triangular Plot
A triangular plot makes it easy to show the relation between three variables. This above graph does show different voting styles with the center dot shows what was expected by the voters.
Wind rose
A wind rose is used to give a view how wind speed and direction are distributed in a location. The site I found this example on had multiple other example of how a wind rose is used and calculated.
Climograph
Climogaphs displays the monthly precipitation and and temperature conditions for an area. The precipitation is represented by the bar graph and the line graph shows the temperature. The above graph is a representation of an Arizona regions precipitation.
Similarity Matrix
Similarity matrix shows similar genes on a scale of 0 to 1, as seen above. The greater the similarity of two objects the higher the value of measure.
Parallel Coordinate Graph
Parallel coordinate graphs is used to visualize multidimensional data and can be used to explore the relationships among variables. There is a connection throughout the graph with the information.
Box Plot
A box plot can go by different names. It a great and simple way to display five areas of information. In one look you are able to see the min and max amounts, the average of the information, and the bottom 25% and top 75%.
Population Profile
A population profile is a chart showing the of people in the the age group. This above graph represents industrialized countries only.
Scatter Plot
Scatter plots are a relationship between two variables. There can be a common trend in most scatter plots if the dots head upward as in the graph above then the graph is positive. If the graph is downward then the graph is negative.
Index Value Plot
An index value plot is a type of visualization map. It depicts the relativity of all values to an indexed value. This map shows the averaged stream slow in North Carolina.
Lorenz Curve
This an Accumulation Plot or it can also be known as a Lorenze Curve. The dark line represented in the graph is the lorenz curve. This above example shows household incomes and expenditures, it does contain more information then a basic graph but you are to see how it works.
Bilateral Graph
I was unable to find a bilateral graph that was not already saved to someones blog site. These graphs are used to represent two variables that are related to each other. While one rises the other decreases and this is what can be seen one the graph.

Pie Chart
A Pie chart is an example of geovisualization. This is an example of countries involvement in Antarctica. By walking in a complete circle around the South Pole you would be able to visit all the claims made on Antarctica.
