Bar Graph

http://scienceray.com/mathematics/the-difference-between-a-histogram-and-a-bar-graph/
  A Bar graph compares specific items of data on an X and Y axis. For this Bar Graph, the X axis represents the type of brain region and the Y axis represents the receptor binding. 

Cartographic Animation

  Cartographic Animation, as depicted above, is used to demonstrate movement across land that would otherwise be very difficult to communicate or explain. We see this animation most commonly from our weather person on the news showing the movement of Low pressure or High pressure air and how that should effect our climate. 

Standardized Choropleth Map

The data in this choropleth map is standardized to allow comparison of distribution among the different areas in the United States. In this map, the morality ratio is standardized in order to show reliable, high risk clusters of cervical cancer.

Index Value Plot


  This index value plot shows the US Dollar or USD fluctuation over the last 20+ years. Notice it has ranged between 90 and 120. Currently this shows that our Dollar has "rallied" or made a positive increase in value recently. 

Infrared Aerial Photographs

 These brightly colored Infrared Aerial Photographs show great detail about the Earth's land formations, resources and vegetation. These photos allow for the accurate mapping of ground cover and are usually taken from satellites like those in the Landsat program. 

PLSS Maps

  A Public Land Survey System is used in the United States to survey and identify land parcels, especially for making titles and deeds of the land. This particular image is from Google Earth showing the PLSS from an aerial photograph taken from a satellite. 

Classed Choropleth Map

  A classed choropleth map is a type of choropleth map that separates the data into small intervals. It is broken down into a scale and presented using colored intervals to visually demonstrate the variation among intervals. In this map there are 5 intervals that are identified using five different shades of pink. These intervals break down the amount of spending in millions by residents of Great Britain.
