Population Profile

 A population profile, also known as a population pyramid, displays age and sex distributions in a specified region. The population profile above represents the age and sex of the population in Botswana, Africa. Additional information is provided in this graph as it also depicts how much of the populace has AIDS. This type of graph makes an amazing geovisualization tool as you can visually see the impact of AIDS in this area.  

Scatterplot

A scatterplot is a graph that plots two different variables and is used to show relationship between the two variables. The scatterplot above depicts shoppers per 15 minute intervals from a store opening. This specific graph can be used to predict when the highest volume of shoppers will utilize the store to ensure maximum employee coverage.

Index Value Plot

An index value plot uses index value instead of absolute numbers. In the index value plot above, the index is a zero value and the departures in the index are plotted relative to it. Positive increases (blue) indicate La Nina conditions and Negative decreases (red) indicate El Nino conditions. The line going through the graph represents the 12 month average southern oscillation index.

Climograph

A climograph is a combination of a bar graph and a line graph that show temperature and precipitation for a given location over the course of a year broken down by complete months. The climograph above depicts average annual temperature and precipitation for Boulder, Colorado with the bars representing precipitation and the line representing temperature. You can clearly see that the hottest average month is May and the month with the highest precipitation is July.

Triangular Plot

A triangular plot is a graph that measure three variables (one for each side of the triangle). This type of plot is commonly seen in geological studies to depict the relative compositions of soils and rocks. The triangular plot above uses different compositions as the variables for sand analysis. The numbers on the sides are scaled as percentages of the given composition and the inside is divided into 12 regions of USDA-specified soil textures.

Wind Rose

A wind rose is a circular plot that shows the strength and frequency of wind from various directions in a given location or region. The wind rose above depicts wind frequency and strength from different directions within the Wilkes-Barre/Scranton International Airport, PA area.

Stem and Leaf Plot

A stem and leaf plot is one famous method for organizing data that encompasses sorting the data and graphing it at the same time. As the above stem and leaf plot shows, the leading number, which in this case is the tenths portion of the number, falls under the stem portion of the graph (left side). The remaining portion of the number, which in this graph is the ones place, falls under the leaf portion of the graph (right side). The graph above conveniently placed a key to show how the read the graph presented.
