Univariate Choropleth map

This map focuses one one thing, poverty. It shows in stark relief the number of people living below the poverty level in this country. It also shows a shape of large amounts of poverty stricken people in the southern part of the country. http://www.cdc.gov/pcd/issues/2007/oct/07_0091.htm

Bivariate choropleth maps

This map utilizes colored shading to depict median home prices in Ohio by county. The twin to this map utilizes the same methodology and geographical region to depict population by county, make the pair "bivariate."

Bilateral Graph

This shows the effectiveness of a bionic ear implant over time. The variants here show side by side the number of correct answers (to a given aural quiz regarding sound localization) given by individuals with the implant over time. http://www.advancedbionics.com/CMS/Your-Journey-to-Hearing/Bilateral-Research.aspx

Unclassed choropleth maps

Utilizing a more varied degree of shading one color, this map depicts fertility rates for European countries. The country is represented by one average that can be matched by shade to the key to determine approximate number of children per mother.

This index value plot shows the worth of Disney Stock prices over time (in this case from Sep 1966 through Oct 67). As we can see in 1966 they were still fairly low, but since then have experienced unprecedented growth, followed by one small period of decline, and then further growth. http://www.loricatrade.com/articles/risk-management-investigating-stops/

Range graded proportional circle map

This map, shown in six parts, depicts six different types of element abundance rates in the same geographical region of Canada. These illustrations also provide a comparison in the source of the minerals between ore and county rocks by using the color of the representative circle.

A very simple scatter plot that shows the effectiveness of practice. A fared in line would show a sharp decline in mistakes with increases in practice. http://ritter.tea.state.tx.us/student.assessment/resources/online/2006/grade8/math/8math.htm

Continuously variable proportional circle map

This map, shown in four parts, utilizes the same geographical representation and methodology to show the presence of four different types of metal elements in the sediment of river basins in a region of Canada. The variable between the maps are only scale and element depicted.
