This type of graph is suited to demonstrate the relationship between three different variables. If you are a registered voter in the U.K. you might be interested in the graph above that shows how voters are leaning in their general election from a poll taken in April, 2005.

Windrose

The windrose is a tool that has been used for a long time. The wind rose as depicted above is a modern version that depicts wind speed in different directions. The windrose usually shows 16 main directions such as North, North by North East, North East, etc.

Climograph

This is a climograph of the savannah in Chipata, Zambia. A climograph is a visual representation of weather conditions of a particular area over time. Rainfall and temperature are the variable shown in this climograph. The bar graph represents rain and the line graph denotes temperature. By Florida standards Chipata, Zambia is a very dry environment.

Population Profile

The population profile above represents the entire population of East and Southern Africa of males and females by age. This visual representation also shows the numbers of those infected with AIDS. According to this graph the largest age group is 20 to 25 for both sexes. This group also has the highest incidence of AIDS. It is interesting that at age 75 through 80 almost everyone has AIDS; strange.

Scatterplot

A scatter plot is a visual display that uses data of two separate variables; they are plotted on a graph as a collection of points from values that correspond to the X and Y axis. The scatter plot above is a comparison two types of SMO; a 95 and a 96. To be honest, I have no idea what an SMO is, nor do I care; I chose this because I like the colors.

Index Value Plot

An Index Value Plot is an image of data represented in the form of a graph. The index value is plotted on the Y axis while the date is plotted on the X axis. The Index Value Plot above shows a comparison of closing levels of the world market from 1992 through 2004. This shows Germany beating the pants off of the competition; farfegnugen!

Accumulative Line Graph or Lorenz Curve

http://www.qualityinfo.org/olmisj/ArticleReader?itemid=00003899

The Accumulative Line Graph of Lorenz curve is a graph that shows a probability of distribution. This type of graph id usually used to show income distribution as is the case in the representation above. The curved portion of the line depicts the higher wage earners and can be used to relate an example of social inequality.
