Bilateral graphs depict two or more variables. They show this in much the same way as a bar graph or line graphs.
Triangular plots depict the way three variables interact with eachother. This is often used in geology as a way to show the way three different types of rocks can combine. The map to the right shows the ways in which political demographics were split
Climographs show the average monthly amounts of precipitation and correlating temperatures. This map of Hawaii shows and average temperature of around 70-80 degrees year round while precipitation changes with seasons
Windrose incorporate a rose compass overlain with the direction and power of winds. This is used most often by meteorologists to predict and study weather.
Parralel coordinate graphs are perhaps the most difficult and complex graphs within this catalogue. Parralel graphs depict multivariabled data, with each point having its own y/x axis with lines connection each observation between variables.
Population profiles show the change in population by age. This is done through the use of a census.
In this profile you can see that while there is a greater number of younger males then females, females outnumber males later in life.
Scatterplots show correlating data by the placement of dots. This map shows the correlation of the ages of wife and husband.
Index value plots show differences between points of data. This is very similar to a line plot, but instead the lines are closer together. You see these types of map showing seasonal changes in environmental maps.
Propoganda maps are not true maps. While they map have the same general shape (although not often) they are often distorted to show different views of an idea.

Box plots compare data by size of the box. While box plots are good for comparing a generally large number to smaller numbers they are not as concise in numerical data as other maps.
A similarity matrix is similar to a correlation matrix. Instead of using many values and portraying those closest in correlation, a similarity matrix depicts two values and how they are similar.
Correlation matrix maps take large amounts of data and combine them in a square chart. The values that are most correlated to each other are closest and usually shown by similar color rangeds.

Stem and leaf plots are bes for showing numerical values. By placing the greatest 10s place of the value in the stem of the plot, you can add the smaller value to the other side. So instead of writing out a bunch of numbers, this plot looks a lot more organized.
Star plots show information in a way similar to pie charts. But instead think of it as a bike tire on which you can wrap strings around to show the proportional amount of data.
Unstandardized choropleth maps are maps that have not been areally averaged. this map shows water withdrawal.
Standardarzed choropleth maps are used to compare variable data in the form of distribution. This map shows the population percentage of people 14 and under in Canada
Univariate maps, like the name suggest, show only one variable on the map. This map shows the result for the 2004 Presidential election
Bivariate maps are choropleth maps showing TWO different variables on the same map using different symbols. These are best for contrasting variables.
Unclassed choropleth maps are similar to classed but are a much bigger scale. Because the scale is much bigger numbers on unclassed maps the numbers depicted by the map are much less acurate. Unclassed maps have not been aerially averaged.
Classed choropleth maps show areal units that are combined into smaller numbers of groups. These smaller groups can be counties or cities.
These maps use variable sized circles to show amount of data direction proportion to the size of the circle. These maps are great for a specific scale.
Digital orthoquarter quads are forms of aerial photos. Part of the raster mapping family, they can also be forms of color infared maps.
DEM or digital elevation model are most often 3d representations of ground terrain or shaded relief maps. They are a type of topography map, showing the lay of the land.
Digital line graphs combine planimetric and vector maps. They're very often used by the USGS, United States Geological Service to view roads, rivers, along with boundaries
A DRG is a digital raster graphic map. It is basically a scan of a topographic map with lats and longs lines.
Isopleth maps are a type of thematic map. They show continuous lines that connect points of equal value. These values can be anywhere from temperature to rainfall, etc.
Isopach maps show the vertical thickness of rock. This is especially useful for mining and drilling.
Isohyet maps show areas with equal amount of rainfall and precipitation. This is shown over a period of time of months or a year.
Isotach maps show areas of equal wind speed.
The area darkest in color is the area with the highest wind speed
Isobar maps are a type of weather forecasting map. The isobars show areas of same atmospheric pressure and also show areas of high and low pressure.
LIDAR or light detection and ranging uses laser pulses to determine information such as distance and range of a specific target. Information such as distance is determined in much the same way as echolocation, measuring the time it takes for the laser pulses to bounce and return. This is a LIDAR map of Manhatten.
Dopplar radar is used primarily in showing weather patterns over a certain area. This is especially useful in the forecasting of hurricanes over a large area. We know this very well because of the large amounts of hurricanes to pass through Florida.
Black and white aerial photography is used to see the basic layout of the land. The darker vegetation and come up black while cities and urban areas you can see the layout much easier.
Infared aerial photos are used mostly to view vegatation and changes therein. In a way this is kind of a chloropleth map because it uses variations in color to signify changes. this is especially used to signify the amount of change global warming has had on forest vegetation.
When I think of cartographic animation i think of the animations
of hurricanes. 
and weather channel. Also see my chloropleth for another example.

Statistical maps show the variation in the data. This is very similar to thematic, dot distribution, and chloropleth maps.
Cartograms are a type of thematic map, with one twist. While showing differences in the mapping variable by different colors, it also distorts the map to show the size of the mapping variable compared to the land.
Flow maps often show the movement of something from one location to another. This can be anything from population to the selling of goods.
Dot distribution maps are best in showing changes in number data across a map. This map shows the number of metropolitan poor, mostly isolated on the east coast.
Isoline maps show areas with equal numbers through the use of continuous lines. Eamples would be temperature, barometric pressure, and altitude.
Proportional circle maps show data as a relation of size to number. The larger the size of the circle, the number should be that large in proportion

Chloropleth maps are maps that show differences in
values using shading, coloing or patterns. In this way they are very similar to hypsometric maps (which shade according to elevation)

Hypsometric maps are in essence just topographical maps. But the difference between the two is the shading that is often seen on hypsometric maps to signify the different changes in contours. I picked this map because, well, quite frankly, it was a beautiful map, very pleasing to the eyes.

PLSS or public land survey maps are used to map out land parcels mostly in rural areas, often mass farming land. PLSS is often counted in parcels, sections and townships. As you can see in this map, the larger parcels of land correspond rather closely to lines of latitude and longitude.

Topographic maps are my favorite maps to read.
I actually have started a small collection of these
maps as well. Topographic maps show relief and
changes in elevation from sea level.
