Air Travel Map

This map shows the different routes for an airline company. This is a type of flow map, however all of the lines are the same thickness. This does not allow the reader to know which route receives the highest rate of traffic by aircraft. Also, relief is used in this map, showing where the different mountain ranges are located.

Social Network Map

This is a figure that maps out how people communicate with each other and who communicates with eachother. While this is a type of flow map, it is quite unique in its usage. A rumor could be traced back to its origin using this map.

Cartographic Animation

This image is the projected path of a hurricane. Land is predicted to expand the projected path of the hurricane, making it highly affected by land. This allows viewers to prepare for an intense storm.

Isopleth Map

This map shows the average wind speeds along the coast of the Southeastern portion of the United States. Color enhances the depiction of the information and no drawn boundaries are created in the map. The greastest wind speeds are offshore to the East.

Thematic Map

This is a thematic map of the United States that shows different regions of the United States that have experienced population changes. This map also shows histograms and proportional dot size to further relay information to the reader. There is a scale at the bottom of the map to keep everything in perspective in the map.

Planimetric Map


This is an example of a planimetric map of a town. It shows the roads from an areal point of view and is to scale. It also shows buildings that are points of interest. It is only a two-dimensional view and does not include any relief or contour.

Isolines

This is a map of China which uses isolines to determine the amounts of runoff rainwater. Each line collaberates with a number to present the of runoff water. The largest amount of runoff is located in the Western side of the country where the large mountain range is located. In addition to the isolines are lines for longitude and latitude.

Mental Map

Here is an example of a mental map that directs the user to get to Gettysburg. It is not to scale, however it depends on landmarks to be an effective tool for the user. Also, the fact that it is handdrawn adds to the fact that it is a mental map.

Unstandarized Choropleth Map

This map shows vacancies in different sections of a state. There are some areas that are not covered by the color, leading the reader to assume they are no vacancies in this area. It is considered unstandardized because it has not been areally averaged.

Digital Raster Graphic

This image shows the roads in addition to contour lines which give the map elevation. Labels are seen throughout the image, such as the river and areas of the town. It is a scanned image of a topographic map.

Digital Orthophoto Quadrangles

This is an example of a color areal image. It uses infared film to create the infared image. This type of photo allows the viewer to distinguish different types of foilage, terrain, or bodies of water. The color seen in this photograph is actually false because infared wavelengths are unable to be seen by the naked eye.

Parallel Coordinate Graph


This graph shows the trends of a company's employees' money and their age. The darker location on the graph shows that this trend is more common than the areas that only have few lines. Also, the color represents different individuals.

Triangular Plot

This triangular plot describes the diet of New World Monkeys, Old World Monkeys, Gibbons, Apes, and Lemurs. At each corner is an exclusive diet and every group of animals is represented by a unique shape. This table provides the information that the majority of the animals enjoy fruits and seeds, while some leaves, flowers, gum and sap make up a portion of their diet also.

Boxplot

This is an example of a boxplot, which is also sometimes called a whisker plot. It shows the average for the data and also the extremes on each end the data. Boxplots are a very good way to compare two sets of data.
http://www.statmethods.net/graphs/images/boxplot1.jpg

Histogram

This is an example of a histogram, commonly referred to as a bar graph. Histograms have the advantage of showing exactly which ranges are highly populated and which are not. This makes the information easily interpretable.

Arm Span Length

This is an example of a stem and leaf plot. It shows the different arm spans that range from 130 cm up to 172 cm. The advantage of this graph is that it easily displays the average length, which is in the lower 150's.

Windrose Graph

This is an example of a windrose graph. It shows the percentage of whatever speed an object was moving in each direction. Also, this graph uses color to give the range of each individual speed.
http://lion.cs.uiuc.edu/projects/wsn_ornl/windrose.png

Population Profile


Specifically, this graph is called a population pyramid, due to the shape of the figure and the groups of people that it represents. The trend seems to be that AIDS cases increase till the individual is 20 years old then the trend seems to dwindle some what. AIDS has quite the same trend in men as it does in women also.

Climograph

This graph shows the precipitation levels, as well as the average temperature duing each month in Australia. This information correlates to a specific location, Walgett.

Lorenz Curve


This graph shows the values of the cumulative population versus the cumulative income during both the '01-'02 year and '05-'06 year. The perfect equality line is inserted to depict what the equally proportional values would be. The area above the line is considered the equal area and the area below it is considered the inequal area.

Index Value Plot

This type of graph shows the average flows of streams in North Carolina over a ten year span. These averages are comparable to the normal value, which is 4. All of the values following 1999's data is relative to the first value.

Range Graded Proportional Map

This map shows the different population density of each of the counties. The size of each circle corresponds to a specific value, given in the table on the left. This makes the map a range-graded dot density map.

Nominal Choropleth Map

This map potrays areal data and is distinguishable by the boundaries of the states. The fact that the map potrays information that is not numerical, but rather by different categories makes it nominal. This particular map shows four different categories.

Digital Line Graph

This is an example of a DLG. It shows both the topography contour lines and also the roads. The boundary of the gravel pit is also shown.

Isotach Map

This map is considered to be an isotach map because it uses the contour lines to depict wind speeds, rather than terrestrial terrain. However, the lines are still used in the same fashion, that if lines are very close together, then there is a greater change.
http://weather.cod.edu/help/850tach.gif

Bilateral Graph

This type of graph is considered to be bilateral because it shows two types of information being portrayed on the same graph and visualizes the trend of both against eachother. Here the percentage of demand deposits is compared to the percentage of long-term deposits.

Topographic Map

Above is an example of a topographic map. It is a topographic map because it shows the shape of terrestrial terrain. It shows the relief and shape of the land from above through the use of contour lines. The closer they are together, the more extreme there is in the change of height, like a cliff, while if there is distance between the lines, the change is more gradual.

Proportion of Internet Users in Europe

This data is shown by circles. The size of the circle is proportional to the number of internet users in each country. These circles are categorized as being continuously variable symbols.

Unclassified Choropleth


This is a map of the population trends in France in 1836. It is unclassified because it is created using a gray scale and has as many units as intervals.

Scatterplot

This is an example of a scatterplot graph. It includes a trend line that marks the average of the values. There is a positive and weak relationship between the points.
