Lorenz Curve




A Lorenz Curve, sometimes known as an accumulative line graph, is a graph that generally is used to express inequality. Often the subject of these graphs is wealth distribution in a population. A line of equality is drawn to emphasize how severe the differential may be as you can see above.

Population Profile


The image above is a population profile depicting the number of males in Northern Ireland in 1971. The graph spans from zero to ninety years old and in viewing the data in a graph format we are able to see the difference in the population as well as find an age where each gender has roughly the same number of individuals.

Cartographic Animation


Cartographic animations are a great way to show changes and shifts in the Earth's atmosphere or surface over a period of time. By using both cartography and graphic art people are able to present these changes as the animation above shows the shifts of the wind velocity magnitudes on a global scale. Again a shading scale is used to capture these shifts.


Correlation Matrix



A correlation matrix, as the name suggests, is a matrix dedicated to presenting correlations in a pair of data sets based on gathered statistical values.

Similarity Matrix


Similarity plots compare a variety of variables to find patterns within the data collected. The plots generally are used to find similarities present in the data. The image above is such a plot showing relative commonalities between those listed along the graph.


Climograph



Climographs are a unique way to show the weather of a certain region, including temperature and precipitation, in a graph format. They incorporate two types of graphs into one using a line graph to represent the temperature and a bar graph to represent the amount of precipitation as is shown in this climograph of Memphis, Tennessee.

Windrose Diagram



A windrose diagram graphs the direction and speed of the wind in a certain location.  As is shown in this windrose, color is often used to indicate specific ranges of wind speed.
