Standardized Choropleth Map
This is an example of a standardized choropleth map. The above map classifies the Australian climate, each color represents a different type of climate.

Propaganda Map
Propaganda maps are used to sway the onlooker of the map to what the creator of the map wants. In this case, the map is what Ronald Reagan wanted, or the person who created thinks Ronald Reagan wanted, the world to believe.

Popultion Profile
Population profiles are used to identify the life span of males and females of a certain area. The above map is of African and European males and females. Males are represented by the black bars and females by the grey. The longer the bars are, the higher percentage of that age group there are. Population profiles are useful in comparing the age distribution of two areas.

Box Plot
Box plots are useful for comparing multiple sets of data because they can show the minium and maximum values, as well as the 25th, 50th, and 75th percentiles of the data. The box plot above shows the number of daily hospital births in Canada by the day of the week. The line closest to the bottom of each day of the week data is the minimum and the line at the top is the maximum. The horizontal lines inbetween show the 25th, 50th, and 75th percentiles from bottom to top respectively.

A bivariate choropleth map is essentially the same as an univariate choropleth map except instead of having just one set of data it displays two or more. The above map shows the margin of victory for each candidate of the 2004 Presidential election and the voter turnout percentage per state.

Cartogram
A Cartogram is a cartographic technique that alters a map to enlarge or reduce certain zones based on the data. These distortions help to further along the point that the color shades may not be good enough alone for. The above map is of the percentages of threatened and endangered amphibians in the world.

Histogram
Histograms are graphs that display information as bars which is the frequency of the data. The histogram above is the life expectancy of a person living in the United States. The graph shows that the highest frequency of life expectancy is about ninety years.

Windrose Map
Flow Map
Flow maps are used to track the movement of objects from one place to another. In the case of the map above, the different truck routes used are shown. The thicker the lines are, the greater number of trucks that used that route, an advantage for flow maps because it reduces visual clutter.

Choropleth Map
Choropleth maps are the most commonly used type of Thematic maps. They are particularly suited to show data when the area is evenly distributed between set areas, as in states in the map above. The map above shows how much water is used daily by each state.

Stem and Leaf Plot
This is a Stem and Leaf plot graph that the distribution of adult heights for a certain data set. This normal distribution set shows that the adults are average roughly 67 inches tall and as the number of inches decreases and increases, the amount of people at that height decreases. Stem and Leaf plots are used to express quantitative data in a graph.

Topographic Map
The above map is a topographic representation of Mauna Kae, which is the tallest point in Hawaii. Topographic maps show elevation changes over a given section. The closer the contour lines are, the steeper the slope is. Also, if you look at the contour lines they are labeled by how high the given line is above sea level.

Doppler Radar
Doppler radar images are beneficial to meteorologists for use in predicting weather patterns and explaining atmospheric phenomenon. This map is a series of Doppler radar images of Hurricane Katrina as it passes closest to Baton Rogue back in August of 2005. Doppler radar works by sending out bursts of radio waves and then recording the radio waves that are reflected back.
