Classed Choropleth Maps
http://en.wikipedia.org/wiki/Choropleth_map
Classed choropleth maps are thematic map in which areas are shaded or patterned to proportion to the measurement of a statistical variable being displayed on a map. The map above is of the 2004 Presidential Election.

Population Profile
camellia.shc.edu/.../statisticsassign.htm
Population profiles is a chart showing the number of people as a function of thier ages. The one above illlustrates the population profile for Mobile County. The age is divided into increments of 4 located on the y axis and the percentage of each age class to the total population is located along the x-axis.

Index Value Plots show information that happens over time. The one above is that of streamflow over a seven day average in the period of a year.
Lorenz Curve
www.answers.com/topic/lorenz-curve
Lorenz Curve's are graphs showing the concentration and ownership of economic quantities such as wealth and income; it's formed by plotting the cumulative distribution of the amount of the variable concerned against the cumulative frequency distribution of the individual possesing the amount.

Similarity matrices are a matrix of scores that express the similarity between two data points.
Similarity matrices are a matrix of scores that express the similarity between two data points.
Correlation Matrix
yin.che.wisc.edu/images.htm
Correlation matrices describe correlation amoung variables with square symmetrical MxM matrix with the element equal to the correlation coeffient between the variables. The diagnol elements are always equal to 1.
DEM
www.oregonfishingforum.com/other-stuff-relate...
DEM-Digital Elevation Model is a representation of ground surface topography or terrain represntation raster or as triangular irregular network built using remote sensing technique or form land surveying. This type of mapping system is based on digitally produced relief maps.
Cartographic Animations

Cartographic animations is graphic art that occurs in time.
Statistical Map
www.restmap.net/.../MapLinks_ME.htm
Statistical maps show a specific type of map in which the variation in quantity of a factor such as rainfall, population, or crops in a geopgraphic area is indicated. The above map indicates the hardiness of Maine.

Cartogram
http://politicalmaps.org/2004-presidential-election-maps/
This is a cartogram displaying the political map of the US and the states that are democrate and republicans. A cartogram with some thematic mapping variable. As shown in the map above the geometry or shape of the map is distorted in order to convey the information of the alternative variable.
Flow Map
mdianeharrison.com
Flow maps display a sequence or process. The one above show the steps to making a peanut butter and jelly sandwich. When displayed the process seems easy and less confusing. This could be good for teaching simple process or even chores and household duties.
Isoline Map
http://proceedings.esri.com/library/userconf/proc02/pap0167/p0167.htm
Isolines connect points of equal on a map. Like exact values including temperature and elevation, and other ratio values.
Choropleth Map
http://my.ilstu.edu/~jrcarter/Geo204/Choro/Tom/
Choropleth maps are based on predefined aerial units, designed in a multi-colored cheakerboard pattern.
Each group of data displayed and organized in a ratio value, so color graded series is used to show the intensity from greatest to least. the darker the shade of a color the more intense and vice-versa goes for the less intense.
Dot Distribution Map
www.ville-ge.ch/musinfo/bd/cjb/africa/help.php
Dot distribution maps uses dots symbol to show a feature or phenomenon. This type of map rely on a visual scatter to show spatial pattern as shown in the map above.
Propaganda Map
Propaganda maps are used as persausive cartography. These maps are usually created for poltical propaganda as a means to sway the opinions of the people.
This made itself shows how people percieved that Germany would be attack, false representation can lead people to believe false information as done so in this map.
PLSS Map
PLSS- Public Land Survey System is a way of subdividing and describing land in the United States. PLSS is used to divide public land domain, owned by the Federal government for the benefit of the citizens of the US. PLSS land domain is subject to subdivision by a rectangular system of surveying.
Cadastrel Map
Thematic Map
Topographic Map
Planimetric Map
Mental Map
A mental map refers to a person's personal point of view perception of their own world. Each person's mental map is completely different from the next. It's a type of mental processing composed of psychological transformations by which an individual can aquire, code, store, recall and decode information about relative locations.

Scatterplot
picsdigger.com/domain/epsb.ca/
A scatterplot is a useful summary of a set of bivariate date (two variables), usually drawn before working out a correlation coefficient or to fit a line of regression. Its a good visul to see the relationship between two variables, and aids in the interpretation of correlation coefficient or regression line. There will eith be a postive,negative or non- association depending on the relationship between the two variables.
Stem and Leaf Plot
A stem and leaf plot summarizes the shape of a set of data and provides extra details regarding individual data. The data is arranged by value place. The digits in the largest place is referred to as the "stems" and the digits in the smallest place is referred to as the "leaves". This particular stem and leaf plot displays the ages of the people that attended a family reunion.

Star Plot
Box Plot
This simple box plot, this type of graph is usually used in descriptive statistics to display the disturbution of data and the relationship in between based on the five number summary. The image is pretty self explanatory showing the number ranging from the minimun, first quartile, median, third quartile and maximum.
