Unstandardized choropleth maps utilize raw numbers when displayed. In this map that is displayed above shows the race between democrats and republicans in the 2008 presidential election. It is shown above that the democrats won by 40 votes.
A nominal area choropleth map is a choropleth map that displays nominal data. Here is a map with nominal data of Northern Europe in 1939.
Population profile maps present a graphic overview of several demographic statistics collected certain data. They can depict a wide range of variables through different methods. As you can see on the population profile above age distribution is hwon from 1997 and 2005.
A triangular plot displays information in the shape of a triangle. In this example above the triangle is a plot of election votes from 0-100.
A parallel coordinate graph obtains multivariate relations. They are used to show numerous amounts of sets of data. Specific properties of the relationship correspond to the geometrical properties of the graph. 
A bilateral graph depicts increases on one side of a zero line and it decreases on the other side. They are used to display data when there are negative and positive values. On this bilateral graph above it shows how Bush's economic policies effect jobs and unemployment. The bottom line shows how jobs rise and the unemployment rate goes up and on the top line the unemployment rate decreases. 
A windrose is a graphical tool utilized by meteorologists to depict how wind speed and direction are distributed at a specific location. It will show the frequency of winds blowing from certain directions. Each concentric circle stands for a different frequency which starts at zero in the center and increases in frequency in the outer circles. This windrose above shows the speed of wind and its directions. 
A cartogram is a map where area is not preserved. They are used many of times to represent the size of populations relative to the area in which they inhabit. There are two main types of cartograms: area and distance. An area cartogram illustrates the relative sizes of the populations of the countries by scaling the areas of each country in proportion to its population. Distance cartograms are used to show relative travel times and directions from verticals in a network. The Cartogram map above shows the distribution of the populations in the United States. 
This is an Isoline Map which is a map with continuous lines joining points of the same value. They are maps that are a two dimensional representation of a three dimensional model. An isoline map gives you a picture of the concentration of people. The map above shows you the surface dew point temperature which is extremely warm in the south eastern part of the United States. 
This is a Proportional Circle Map that displays data in relation to the size of the circles. In this map data is displayed of internet users in Europe. As you can see from this map above most of the population that uses the internet comes from western Europe while there is little use of the internet in the eastern parts. 
This is a Choropleth Map which shows the use of domestic freshwater including withdrawals and deliveries in 1990. A choropleth map is a thematic map in which areas are shaded or patterned in proportion to the measurement of the statistical variable being displayed on the map. A choropleth map provides and easy way to visualize how a measurement varies across a geographic area or it shows the level of variability within a region. As seen from the map above most of the freshwater use in 1990 came from the states that are by the water including Florida, California, Texas, Illinois, and New York. Most of the north western part of the United States used little amounts of freshwater while Vermont and Alaska used the least of all of them.
This map above is a Dot Distribution Map and displays the numerous amounts of Walmart's throughout the United State and how it is turning into a virus. Dot Distribution Maps are useful to help show populations and portray quantitative data as a dot which represents a number of a phenomenon found within the boundary of a geographic area. The pattern of these dots shows the general locations where the phenomenon was most likely to happen. The pattern and number of these dots shows its density. As you can see from this map Walmart has expanded rapidly in the eastern part of the United States and is starting to build many of its stores in western USA. You can see that the dots are more dense in the south eastern part of the United States which shows the viewer that Walmart feels like most of there customers live in this region. 
This Public Land Survey System (PLSS) Map is used to subdivide and describe land in the United States. The PLSS is used to divide public domain lands, which are owned by the Federal Government for the benefit of the citizens of the United States. The PLSS divides land into 6-mile-square townships. As you can see from the map above it is drawn into a 6-square township and shows the exact meridians and base lines. 
This is a cadastral map which shows the boundaries and ownership of land parcels. Cadastral Maps are designed to make local situations tangible to an outsider and at the same time change reality. As you can see from this map each portion of the land is given its own boundary and clarifies exactly whose land is whose. 
This is a Thematic Map of the United States. A Thematic Map is a type of map or chart that is designed to show a particular theme connected with a specific geographic area. These maps are a great resource to get cartographical information on various themes. This is a Thematic Map which shows the population percent change from 1990-1996. As you can see most of the western part of the United States has changed drastically along with Florida and Georgia. There has been little change in the northern eastern part of the United States.
This is a mental map on Boston, Massachusetts. A mental map is a persons perception of the world. It is an individuals own internal map of their own world. This map portrays how someone that lives in Boston would mentally view the city onto a piece of paper. This mental map of Boston is a map that is created in someones mind. 
This is an Isopach Map which shows thew rock or sediment thickness. It displays the strategic thickness of a rock unit as opposed to the true vertical thickness. This map contains contour lines of equal thickness over an area. As you can see from this map the thickness of the sediment decreases the further away you go from the land. Close to the land the thickness is around 875 and deep into the ocean its at 250.
