A bilateral graph is a histogram that can display different information such as location and amount, on one histogram. They are very useful in side-by-side comparisons. This is a bilateral graph of peoples approval of China's leadership and where the opinion is coming from.
The lorenz curve helps to visualize the cumulative distribution function, and it used mostly in economics. It is most commonly used to show the way income is distributed, and it usually represents the bottom % of households and the amount of money that they receive. 
Scatterplots are used to graph data using the cartesian plane. The data is all selected with the point on the x axis determining where on the y axis the points will fall. All of the individual points graphed together help to give a view of how the data reacts overall.
The population profile is a way to chart data and characterize it in terms of a persons age. Usually it will represent all of the people in the population, and then it will highlight a smaller and more select group. This graph also can help to show how this group is affected over time and with different age groups.
Climographs help to chart the amount of precipitation and the temperature of a certain place over an extended period of time. The amount of precipitation is given by the bar graphs, while the temperature is charted by the line graph. This helps to try and draw conclusions about a correlation between the two. 
The triangle plot is a way so judge how three variables react in relation to each other. The three variables are represented by each side of the triangle and the plots on the inside show how much each variable is represented in the data. This is most commonly used in geology, with the example showing soil composition in different areas, represented by the smaller red triangles.
The parallel coordinate graph is a way to plot a number of different data responses on the same graph. The graph consists of multiple over-lapping line plots that show how similarly the data reacts. This can be most effectively used to see how certain small groups react in relation to how the larger group of data acts as a whole.
Isopleths uses different colors in different spatial areas to represent a numercal scale and its coordinating value. This map represents the different Hydrogen Ion concentrations from across the US.
A stem and leaf plot is a way to graph the frequency of results within a certain data range. The data range is in the left column and in the right column a record of how many times a result lands in that range is tallied. This is an excellent way to show how data is dispersed across a wide range of results.
DRG's are scanned images of USGS topographical maps. This is done so manipulations and other layers may be added to boost the image or present more information. This is a DRG of the Texas State School for the deaf and the area surrounding.
The similarity matrix is a way to measure the similarity between two pieces of data in a series. The variables are listen on the top and left of the graph and a numerical representation of their similarity is given when the two variables intersect; the higher the number, the more similar the variables are.
An Isotach also makes use of continuous contour lines, only these lines are representative of a constant windspeed. This is an isotach map for the windspeeds in canada at the time. Many times these maps can include speed and direction labels also. 
Isobars refers to contour lines on a map that are continuous and represent constant pressures in the atmosphere. This map shows a low pressure cell over the northeast US. 
Lidar is a sensing technology that measures scattered light to determine the objects distance or its form, such as this city scape. It is done with flyovers and is usually done with laser pulses. This is a detailed city scape formed from a lidar image.C1 C2 C3 C4 C5 C6 C7 C8 C9 C10 C1 1.000 C2 0.274 1.000 C3 -0.134 -0.269 1.000 C4 0.201 -0.153 0.075 1.000 C5 -0.129 -0.166 0.278 -0.011 1.000 C6 -0.095 0.280 -0.348 -0.378 -0.009 1.000 C7 0.171 -0.122 0.288 0.086 0.193 0.002 1.000 C8 0.219 0.242 -0.380 -0.227 -0.551 0.324 -0.082 1.000 C9 0.518 0.238 0.002 0.082 -0.015 0.304 0.347 -0.013 1.000 C10 0.299 0.568 0.165 -0.122 -0.106 -0.169 0.243 0.014 0.352 1.000
A correlation matrix is a way to record data for multiple different variables, and to see how all of those variables interact with each other. The matrix has all of the measured variables listed both down the left side of the graph and across the top. Then a statistics program is used to determine the correlation between all of the different variables in relation to each other.

Doppler Radar is a tool that we have all seen on our local news forecasts. It uses the doppler effect and microwaves to produce a picture of storm activity and intensity over a certain spatial area. This a doppler picture of Frederick, OK.
Black and White photography provides a very detailed picture of the land area being shown. It allows for more detail to be shown with the absence of color. This is an aerial of a small city.
Infrared aerial photos are an invaluable tool in the world of mapping. Infrared film is sensitive to a certain portion of the spectrum of light, and this information can provide valuable information about the landscape. This is an aerial of the Sacramento Deep Water Channel.
Cartographic animation is an animation of anything to be potrayed or layered over a land mass. This is a cartographic animation of Hurricane Katrina, a category 5, which was the most devastating hurricane in US history.
The star plot is a mapping tool used in order to compare multiple variables of data simultaneously. Usually star plots contain multiple stars, so that the wide range of data can be compared across a number of different test subjects. The star plot is made up of a number of radii, which all resemble a different variable. The length of the radii represents the amount of proportional data that the unit has, relative to all of the other test subjects. Lines are drawn to connect all of the data points around the star, which is what gives each unit its star-shaped appearance. 
A statistical is can be many different types of maps but are characterized by one thing, they display the differences in a certain variable across a geographical location. The number or color code is usually displayed in its coordinating location. This is a map of the United States and the number of total losses to flood damage. This map not only shows the numerical value on the state but a color range to help with identifying the highest dangered states. 
A cartogram is an odd looking thematic map that trades a variable, such as electoral votes, for actual land size or mass. In this map, the US is shown in proportion to how many electoral votes each state has, with that number dictating how much space it takes up. Also, this map codes each state Republican or Democratic and how strong those respective populations are. 
Flow maps are a representation of a flow chart mixed with cartographic information. They usually show the movement of something such as goods or people and how it is distributed. The wider the flow out of the origin, the larger the value. This is a map of french wine exports in 1864.
Isolines are lines on map that are continous and have a set data value, such as elevation. These lines cannot be broken and sometimes encompass large areas and sometimes smaller areas, depending on the geography. This map is an isoline map of the little smokey lake elevation and the areas around it.
A Proportional Circle map is a very easy map to read and understand. They use circles to represent a value, with the larger the circle being equal or proportional to a larger population. Basically, bigger circle, bigger value. As in this map, which is a map of the US showing the Hispanic population in each state. Each state population is represented with a circle, the larger the circle the larger the population in state.
Choropleth maps are usually very simple with one variable being shown on geographical locations with different colors or different shades. A variable such as population density or per-capita income is the type of thing represented. In this map, the spending of great britian is represented with a variety of shades of pink, pink being most lavishly spending areas. 
Dot Distribution Maps are maps that show numerical data, such as population, with dots across a spatial area. The main idea is not to provide accurate geographical locations of the populations, but to show the population centers and their density. This is a map of the militay family in Ohio, with one dot representing 5 people.
Propaganda maps are maps that are created by a certain party or person with a certain bias. They are created with the idea of influencing others opinions a certain way. This is the case in this map, which posted on an Anti-Drug war site, is arguing against the drug war with a main point that their are more medical marijuana dispensaries in San Fran then there are Starbucks, so it is stupid to waste money trying to stop something we are selling.
A hypsometric map is a map, very similar to a topographical map, show elevations in a certain spatial areas with the use of certain colors for certain elevations. This is a map of the Pamir province and the elevations within.
The Public Land Survey System is a method used in the US to detail the boundaries of different land parcels. It is kind of a cadastral map, but is geared more toward wild and rural land, and private or government ownership. This map is a Bureau of Land Management map that shows the baselines and meridians used for surveying states. 
A cadastral map is a map that shows the owners and boundaries of different land parcels. Sometimes they even go into even more detail as to provide unique indentifying numbers for each parcel such as in this map. This is a cadastral map of beachfront property in Bohol, Philippines, and shows the different land parcels and boundaries along with identifying numbers. 
Thematic maps are usually very simple maps the just convey and particular theme or phenomena, such as population density, over a geographic area. Sometimes they can focus more on the theme or phenomena than actually the geographic data and may use it more as a baseline. This map however, is a fairly detailed depiction of Africa, Europe, and the America's, but it is a thematic map because it displays the lines of equal magnetic variation. It was the first map of its time and was created by Edward Halley in 101.
Topographic Maps are very complicated map and show alot of detail about the place they are describing. They are very similar to planimetric maps but the main difference is that they detail the vertical aspect also. The elevation has historically been shown with contour lines representing the different levels of elevation, but other methods, such as the color contrast method, have been developed to show elevation. In this topographical map of Brazil, the major cities are marked along with major rivers and the elevation is shown with a variety of different colors with each shade of the colors directly cordinated to a scale on the side. As seen, the Rio De Janiero is much hillier than the northern part of the country near the Amazon.
