Parallel coordinate graph


www.matthewtavares.com/baseball_report/

A parallel coordinate graph is a graph that plots its variables on a vertical axis and is particularly helpful when plotting large amounts of information and showing the relationships of it. Each piece of data is shown on a y axis and has a maximum point shown at the top. This parallel coordinate graph shows baseball statistics.

Triangular plot

Scatterplot

www.netmba.com/statistics/plot/scatter/

A Scatterplot is a graph that shows the relationship between two variables using a line and dots around the line in most cases. The dots can indicate a strong relationship if they are close together and close fit, and also indicate a weak relationship if they are not close fit. The graph above shows a positive relationship.

Index value plot


water.usgs.gov/waterwatch/?m=pa07d&w=plot

An index value plot is a graph that is used to compare different averages to a particular year of data and give the different relative to the index value, or compared data. It uses a system of averaging out all the information except the index value and multiplying it by 100. This graph shows the average streamflow of water relative to the historical streamflow of water.

Accumulative line graph or Lorenz curve

www.frdp-maldives.gov.mv/hies/cover.htm

A Lorenz Curve is a graph that can show the amount of a variable of data, usually income, if the data was distributed equally out, and also show the actual distribution in order to show how disproportionate in most cases social financial stats actually are. This Lorenz Curve shows per capita household expenditures in 2002 and 2003.

Bilateral graph

www.globalhumanitarianassistance.org/humanita...

A bilateral graph is a graph that shows the variable as a positive or increasing number and/ or a negative or decreasing number, such as population. In this photo, from 2005 to 2006, you can see the growth in humanitarian assistance as well as the negative dips.

Unstandardized Choropleth Map

www.adherents.com/rel_USA.html

An Unstandardized Choropleth Map shows the map aerially and divides the area like standard maps, however they do not rank the category or give specific numbers or percentages regarding the data. This map is of the United States and shows each state and the most largest religious group in that state.

Standardized Choropleth Map

www.lib.utexas.edu/maps/united_states.html

A standardized map will show a set of data from an areal perspective using a specific and standardized unit. The map above shows the percent of total population of Spanish people for each county of the United States. The percent per total population is the standardized unit being used.

Bivariate Choropleth Map


A bivariate choropleth map is a type of simple choropleth map that combines two types of data at the same time. They do this by using two sets of symbols or colors on the map. This map is an example of just that.

Unclassed choropleth map

http://www.mapresso.com/examples.html

An unclassified Choropleth map is an areal shot of data mapped in as many intervals of color as there are aerial units. The above map is from a unclassed mapping website and shows election results in 2003 in South Tyrol, Italy.

Range graded proportional circle map

http://www.iupui.edu/~geotech/g337/g337_old/exer7/exer7.html

A range graded proportional circle map is a map that uses circles and a key to give certain types of geographic information such as population, industry, cattle, and so on. The thing that separate range grades from a continuously variable proportional map is that there is a set number of circle sizes that are used. The map above shows the gross domestic product in the world from 1996.

Continuously variable proportional circle map


mapmaker.rutgers.edu/355/links.html

The above image is a continuously variable proportional circle map of the Illinois, Michigan, Ohio, and Indiana corners. This type of map uses circles that are sized in correlation to the amount of whatever data is being given in that area. In this map, the biggest circles are around Chicago and Detroit because of their dense population.
