Star Plot

http://en.wikipedia.org/wiki/Radar_chart
This plot is used to display multivariate data. Each star or point is a single peice of data that is linked together by lines. This makes it easy to view relative values between multiple plots. This is a NASA star plot dealing with the MER IDD robotic space arm.

Stem and Leaf Plot

http://mainland.cctt.org/mathsummer/JosephBond/StemAndPlots/stem-and-leaf_std.htm
This plot type is used for displaying numerical quantitative data. It is used frequently in statistics. This specific map depicts infant mortality rates in Western Africa.

Box Plot

http://www.numeracy-bank.net/?q=t/stt/mwu/4
This Box and Whisker Plot shows the measurement of bone density between the two sexes. These graphs are good for showing outliers (even though this plot doesn't have any). They are mostly used in Math applications.

Histogram

http://labwrite.ncsu.edu/res/gh/gh-bargraph.html
This Histogram depicts the United States female population in 1997. Bars are used to show the distribution of ages in the population.

Parallel Coordinate Graph

http://hci.stanford.edu/jheer/files/zoo/
This Parallel coordinate graph deals with vehicles from 1982. These complex maps allow multiple variables to be analyzed in the second dimension.

Triangular Plot

http://www.dplot.com/triangle-plot.htm
The Triangle plot shows three different variables on an equilateral triangle. This plot has clay, silt, and sand as its axises. The plot can be used to compare and contrast three different variables.

Wind rose

http://en.wikipedia.org/wiki/File:Wind_rose_plot.jpg
This is a Wind rose for La Guardia airport in New York 2008. The spokes show the direction and speed of the wind on average throughout the year. The wind here blows the strongest south.

Climograph

http://www.colorado.edu/geography/extra/geogweb/bouldercreek-2/preview/page2.html
This graph is used by meterologists and climatologists; it plots the weather. More specifically it shows precipatation and temperature over a time period. This map shows data for Boulder, Colorado.

Population Profile

http://2010.census.gov/
This chart shows the 2010 census data for Washington DC. The chart shows the population with ages as the function. It seperates male and female data sets.

Scatter Plot

Index Value Plot

http://www.worldclimatereport.com/index.php/2010/07/29/recent-news-from-antarctica/
The Index Value Plot is used to identify and map data outliers. This map shows the snowmelt in the southern hemisphere and the melting index. These plots can be handy for climate change scientists.

Accumulated Line Graph

http://library.thinkquest.org/05aug/00282/over_measure1.htm
This Accumulated Line Graph includes the Lorenz Curve. The data represented is income inequality in 1978. The straight orange line is where Lorenz thought the utopian society should be and the blue B curve is where the US is. According to this map everyone does not have equal income, but at least no one has all of the money.

Bilateral Bar Graph

http://www1.eere.energy.gov/vehiclesandfuels/facts/2008_fotw546.html
This Bilateral Bar Graph contrasts the global auto sales from 2007 to 2008. It has both positive and negative bars and a central axis of 0%.

Nominal Area Choropleth Map

http://www.vbmap.org/europe-maps-9/world-maps-europe-33/
This Nominal Area Choropleth map shows Western Europe and only shows names. This means that there is no numbers involved so the data is Qualititative. Different colors are used to show different states, not different data so its a Nominal map.

Unstandardized Choropleth Map

https://www.e-education.psu.edu/geog485vba/l7_p7.html
Even though this map is of the same data as the standaradized choropleth map it uses the raw data to show state population. This map hasnt been normalized or the data average so therefore its a Unstandardized Choropleth Map.

Standardized Choropleth Map






https://www.e-education.psu.edu/geog485vba/l7_p7.html
Standardized Choropleth Maps use set ranges to break down the variable into percentages and averages. This allows the data to be mapped easily and simply. The map above shows US population in 1999 per sqaure mile.

Univariate Choropleth Map





http://www.gisdevelopment.net/application/urban/overview/urbano0032.htm
This Choropleth map only shows one variable. They are the most simple type of Choropleth and are very frequently used. This map shows some sort of difference between counties.

Bivariate Choropleth Map





http://rkpjrhist615.wordpress.com/category/geography-310/
This type of map represents two data sets with different symbols, in this case colored squares and gas pumps. It is used to compare and contrast the variables.

Unclassed Choropleth Map

http://www.math.yorku.ca/SCS/Gallery/milestone/thumb5/popup/bssn1_popup1-18.htm
This map uses a scale of shading instead of specific values to represent data. The map above is one of the first Unclassed Choropleth maps and was created in France 1826. These maps aren't really used by modern cartographers.

Classed Choropleth Map

 

The Classed Choropleth Map uses averages of water withdrawals in 2000. It also exists within boundaries of the US.

Range Graded Porportional Circle Map

Continuously Variable Proportional Circle Map

http://similaritymatrix.blogspot.com/2009/11/continuously-variable-proportional_29.html
This CVPC map uses circles to represent data, in this case voter preference in the 2008 campaign. This changed as the results came in.

Isopleths

http://www.unc.edu/~meagsmch/ozone/o3isopleth.htm
An Isopleth is any contour line that connects points of equal value to each other. The map I chose was an ozone thickness map which uses the lines to represent the areas of thickness.

Isopachs

Propaganda Map

http://publicdiplomacypressandblogreview.blogspot.com/2011/11/november-20.html
This Propoganda map depicts Europe pre-WWII. It appears to be a Nazi propaganda map showing all of the other states ganging up on Germany after WWI. This was used as a tool to persuade the people of Germany to elect a certain party. It distorts the scale and the design is very subjective.

Hypsometric Map

Mental Map

http://soa.utexas.edu/work/eaejp/methods.htm
This Mental map depicts the area around a 6th graders school. It qualifies as a mental map because it was drawn purely by the students perception. The map is a perfect representation of a mental map and shows evidence of human spatial distortion.
