Planimetric Map (II)

Although I have already posted a planimetric map, I wanted to post just one more.  The above map is a planimetric map of the Naval Academy in Annapolis, MD, where my little brother is currently undergoing plebe summer (a form of boot camp)!  You know the above map is a planimetric map because this map represents only the horizontal positions of features (without their elevations).

Unstandardized Choropleth Map

An unstandardized choropleth map is another thematic map that displays data sets with shading and coloring.  In an unstandardized choropleth map the data sets are shown as raw numbers. Instead of averaging the data, in an unstandardized choropleth map, it is represented as its original value.  The above map is an unstandardized choropleth map illustrating unemployment in the United States in the year 2008.  Using this map you can infer that the state of Michigan has the highest number of unemployed citizens.

Nominal Area Choropleth Map

The above map is a nominal area choropleth map.  As mentioned before a choropleth map uses differences in shading, coloring, or the placing of symbols within predefined areas to indicate the average values of a property or quantity in those areas.  Nominal scale: The differences in data are only of qualitative nature, for example: differences in gender, language, land use or geology.  The above nominal area choropleth map shows access to safe drinking water.

Bilateral Graph

A bilateral graph is very similar to a bar graph or a histogram however it is, of course, bilateral.  Bilateral graphs compare two or more sets of data in a visual graph.  Sometimes bilateral graphs have multiple bars side by side and some bilateral graphs have bars that are opposite one another.  The bilateral graph seen above shows the bars side by side and is a bilateral graph of Disney open, high, low, and close prices.

Accumulative Line Graph or Lorenz Curve

The Lorenz curve is used an economics and is defined as graphical representation of the cumulative distribution function of the empirical probability distribution of wealth.  This means that it is a used to represent income distribution and therefore the inequality in wealth.  This graph is formed by plotting the cumulative distribution of the amount of the variable concerned against the cumulative frequency distribution of the individuals possessing the amount.  The Lorenz curve shown above illustrates the cumulative share of the income earned by people from lowest to highest incomes.

Index Value Plot

The easiest way to understand an index value plot is to first best understand what an index is.  In index is a statistical indicator or number derived from a formula, which is used to characterize a set of data.  An index value plot is a type of visualization map that is plotted on a line graph.  What an index value plot allows one to do is look at variations over a situation.   The above index value plot shows the rainfall recorded in inches in Oregon from 1999-2006.

Scatter Plot

A scatter plot is also known as a scattergraph.  A scatter plot is a mathematical graph of plotted points that show the relationship between two sets of data.  These points, or dots on the graph, show correlation between two variables.  As you can see from the above scatter plot the points on the graph show correlation between car weight and miles per gallon, something that can be very, very practical with today’s gas prices.
