A Stem and leaf plot is a device for presenting quantitative data in a graphical format, similar to a histogram, to assist in visualizing the shape of a distribution.
A graphical summary of numerical data sample through five statistics: median, lower quartile, upper quartile, and some indication of more extreme upper and lower values
A triangular plot is a barycentric plot on three variables which sum to a constant. It graphically depicts the ratios of the three variables as positions in an equilateral triangle.
A Lorenz curve is a graph showing the proportion of the distribution assumed by the bottom y% of the values. The curve represents the cumulative distribution function of the empirical probability distribution of wealth.
A standardized choropleth map is a map that shows the distribution of a data, usually with various colors; color changes are correlated to the density per unit area of the data.
Bivariate mapping is an important technique in cartography, that employs two variables on a map by combining two different sets of graph symbols or colors.
A continuously variable proportional circle map is a proportional circle map which use circles as point data on a map. The circles are proportional to the the data measured.
Digital Raster Graphic. An image (topographic map) of a survey of land. An image of a USGS topographic map that has been scanned and digitized for viewing electronically.
Light Detection And Ranging. LIDAR is an optical remote sensing technology that measures properties of scattered light to find range and other information of a distant target.
A Doppler radar is a radar that makes use of the doppler effect to produce velocity data about objects at a distance. A Doppler radar beams a microwave towards the target and listens for its reflection, then analyzes how the frequency of the returned signal has been changed by the object's motion.
Photography taken from the air where an infrared optical system projects an image directly on infrared film involving point-to-point variations in temperature of an area.
A flow map is a graphical representation of a process. Each step in the process is represented by a different symbol and contains a short description of the process step. The flow chart symbols are linked together with arrows showing the process flow direction.
Propaganda maps are maps created for political propaganda measures. An example would be Nazi Germany changing the perception of threats to keep he U.S. neutral in World War II.
A topographic map is a type of map characterized by large-scale detail and quantitative representation of relief, usually using contour lines in modern mapping, but historically using a variety of methods. Traditional definitions require a topographic map to show both natural and man-made features.
