Schematic
A schematic detailing a concept layout for a housing blueprint. Schematics can map the location of structural elements and their order of placement.

Periodic Table of Elements
The periodic table of elements maps the name and abbreviation of an element to information such as its atomic number and weight.

Portolan Chart
A Portolan chart detailing the Earth at latitudes near the Tropic of Capricorn. Portolan charts were early European navigational maps that combined the practical application of accurate navigational elements (such as detailed shoreline contours) and decorative illustration.

Bathymetric
A bathymetric chart of the Hawai'ian island chain. Bathymetric maps detail underwater topographic information such as the contour of the ocean floor and rising sea mounts.

Similarity Matrix
A Similarity Matrix is a matrix of value scores representing the similarity between a given two data points. Data is mapped across both the X- and Y- axis allowing a row/column comparison of values. In this example darker red colors depict higher levels of similarity.

Stem and Leaf Plot
Stem and Leaf plots are graphical representations of quantitative data used to help visualize the shape of distributions. Unlike histograms stem and leaf plots maintain data in their logical order and to at least two significant digits. This stem and leaf plot is a fictitious example with no specific data being described.

Box Plot
Box plots graphically describe groups of numerical data through their five-point summary (smallest observation, lower quartile, median, upper quartile and largest observation). The spacing between each of the five points describes the size of dispersion between observations and helps to identify outlying data. This map describes some unknown variable observed over a 12-month period.

Histogram
Histograms graphically display frequency data in a bar graph format. As opposed to a typical bar graph, histograms represent information as a function of the total area of the bars rather than a vertical Y-value. This is an important distinction to make when data categories are of non-uniform widths. This example tracks company resources in terms of manpower hours for the fiscal year 2005-2006.

Parallel Coordinate Graph
Parallel Coordinate Graphs plot an entire set of data observations on a single graph. The true power of such visualizations lies in highlighting trends that deviate from the average data path. In this example 6 discrete properties of various automobiles are described. The red tracks are highlighted "outliers" representing perhaps a luxury brand that exhibits aggregate properties outside of the industry norm.

Triangle Plot
Triangle plots are used to map three-variable systems in a given space. Each vertex represents a 100% proportion of the variable to its left and a 0% proportion of the one to its right. This example shows the genetic variation within populations of Native American, European and West African descent. African Carribeans in this case are nearly 100% descendant of West African origins.

Climograph
A climograph map detailing weather data for Manaus, Brazil. Climographs are graphical representations of both temperature (depicted as bars) and precipitation (depicted as a line) together in a given area.

Population Profile
Population profiles are graphical representations of demographic information. This profile shows the projected and actual age distribution of the population of Australia in 2021 and 2002 respectively.

Scatter Plot
Index Value Plot
An Index Value Plot map of fluctuations in the S&P index between the years 1873 and 2003. Index value plots measure data in terms of percentage of a specified average "zero" point rather than absolute numbers.
Taken from HERE.
Lorenz Curve
A Lorenz Curve is used to measure the equality distribution of a given system. This example shows the income distribution of the population of North and South America circa 1996.

Bilateral Graph
A bilateral graph represents both positive and negative values of data in relation to a zero point. This example describes the U.S. trade deficit with China between the fiscal years of 2000 and 2007.

Dopler Radar
A Doppler radar image of the outer storm bands of Hurrican Isabel as it approaches North Carolina in 2003. The image was produced by bouncing and measuring the return radial deflection of radio waves off of the storm front.
Taken from HERE.
Infrared Aerial Photo
An infrared aerial photo of farmland. Remotely sensed photographs taken using infrared-sensitive equipment is useful for easily delineating features strongly responsive to reflection or absorbtion of specific wavelengths of light. Bodies of water and different types of vegetation are two prime examples.

Cartographic Animation
This cartographic animation illustrates the possible storm surge levels predicted for an oncoming storm in Galveston, TX. Cartographic animations help visualize details that would not be apparent looking at a single, static image.
Animation can be found HERE.
Statistical Map
A statistical map showing incidences of homicide throughout various neighborhoods of the metro Denver area. Neighborhoods are color coded according to whether or not they experienced an increase, decrease or no change in events. Rates of change are denoted as numerical statistics within each colored block.
Taken from HERE.
Cartogram
A cartogram depicting the Earth and its major cities, graded as to their perceived cultural relevance as decided by the mapmaker. Cities are here represented as either "Alpha" (most relevant), "Beta" (next relevant) or "Gamma" (somewhat relevant) as shown by the size of their corresponding circles (Alpha is largest). Areas of the planet seen as least culturally relevant have been removed from the map through thematic distortion.

Range Graded Proportional Circle
A range graded proportional circle map showing the number of internet users in Europe circa 2004. Range grading details statistical information in proportional circles designed to represent discrete ranges of data values rather than exact numbers. This allows for circle sizes to be chosen that are easily distinguishable from one another.
Taken from HERE.
Continuous Variable Proportional Circle
A proportional circle map showing the number of ethnic Mexicans in given states. The size of the various circles is directly correlated to the actual population of Mexicans in a particular state according to the U.S. Census Bureau.

Standardized Choropleth
A choropleth describing the percentage of the population under 14 years of age across Canada. This map has been standardized to allow comparison of data across geographic boundaries.
Taken from HERE.
Classed Choropleth
This choropleth represents the colors of fall in the state of West Virginia as seen in four classes (seasonal variation) on a nominal scale with natural breaks.
Taken from HERE.
Unclassed Choropleth
Bivariate Choropleth
A choropleth simultaneously describing two sets of data (bivariate): the life expectancy of populations in Africa as a function of their country's Gross National Product. By utilizing a graded color scheme the problem of representing both spatial and statistical information can be tackled in one map space.
Taken from HERE.
Univariate Choropleth
This choropleth describes a single unit of information (univariate): the total acreage of all forms of hay being harvested in each of the fifty states.
Taken from HERE.
Dot Distribution
This dot distribution map depicts the number of active dentists practicing with a valid Indiana license in a number of midwest states. Each dot represents an equal number of licensed physicians in a given county; higher densities of dots equate to higher numbers of practitioners.
