Standardized Choropleth Map

This type of map is pretty simple and mostly use percentages or ratios to prove a point. The following map show the percentage of people who are Hispanic in the State of Florida. The darker color shows a higher rate than the lighter color.

Accumulative Line Graph

The accumulative line graph, also called ogive, is used in statistics when a person wants to knwo a total at any time. By combining the variables that are given the user can find out the total throughout the process. Here is an accumulative line graph of Lake Waco in 1990-1994.

Box Plot

This is also a certain form of math that is used in Statistics. There are five different summaries that are used when using the box plot: the smallest observation, sample minimum, lower quartile, upper quartile, and sample maximum. Anything outside of these boxes is called an outlier and that is most likely thrown out.

https://www.e-education.psu.edu/natureofgeoinfo/c6_p17.html
According to the USGS Website "The U.S. Geological Survey's (USGS) digital line graph (DLG) files are digital vector representations of cartographic information. Data files of topographic and planimetric map features are derived from either aerial photographs or from cartographic source materials using manual and automated digitizing methods." The following map is from downtown Savannah, GA.
