Population Profile

http://www.ifad.org/operations/regional/pf/aids_1.htm

Population profiles are used to show fluctuations in population as it correlates with age. In the graph above it shows the population density of people with and without aids at certain ages. The largest number of people without aids for both men and women was 0 years of age. The largest number of people with aids for both men and women was at 20 years of age. These profiles allow us to see how age affects the amount of population given certain circumstances. 

Lorenz Curve

The Lorenz Curve is often used in economics. It shows the likelihood of distribution between two variables. The gray area represents the "area of inequality". 

Correlation Matrix

Correlation Matrix's are used to show the correlation and direct relationship between two variables. By putting a variable on each axis you can see the downward slope and correlation.

Parallel Coordinate Graph

http://en.wikipedia.org/wiki/Parallel_coordinates

Parallel coordinate plot is used to show multiple variables data. As shown above, they can sometimes get jumbled up and hard to read because of all the data; therefore, the graphs are used more for showing a high density in numbers rather than specifics. 

Windrose

Windrose's are used to show the distribution of windspeed in a given area. According to this graph, the northwest would be receiving the highest wind speeds. This is shown by using the lime green color.

Index value plot is used to plot data without the data being precise and exact. Its more of a range of data that is used and then plotted accordingly. The type of graph used is a line graph. 

Stem and Leaf Plot

Stem and Leaf plot show the amount or frequency for different values of data. For example, the graph above shows that the three hundreds had the biggest range of data. The stem is the first number and the leaf is the second half. You combine the two for the final number. If the stem is 3 and the leaf is 10 it is 310.
