Climographs are extremely pertinent to weather prediction centers, local weather stations and research. Climographs show monthly precipitation, maximum and minimum temperature, the average temperature in Birmingham, Alabama. The most important correlation is that temperature is compared to precipitaiton.

Digital Raster Graphic (DRG)

 DRGs are a digital image that results from scanning a paper, USGS topographic maps can be used on computers once they become DRGs such as the map shown above. 

Digital Line Graph (DLG)

DLG is a cartographic map feature represented in a digital vector form distributed by USGS. DLGs are collected from USGS maps and distributed in different sizes, with scales with various categories of features depending on the scale. This import of USGS DLG data is showing contours, roads, section lines, lakes and streams from a portion of the  collected data.

Dot Distribution

This dot distribution map was taken in 2000, showing the population distribution in the USA, the scale is one dot=7,500 people. The data collection was done by the 2000 Decennial Census, a part of the US Census Bureau.

Box Plot

Box plots display quantitative data, they are older types of maps but are still used today. They are useful because they show average tendencies, making them especially useful for basic math principles such as upper and lower confidence intervals, and outliers.

Stem and Leaf Plot

Stem and Leaf plot shows the number of students heart rates after one minute of jumping jacks. The stem is the number to the tens, so 15 in the stem section means 150, to that you add one of the number in the leaf section, 1 so the number is 151. Repeated numbers are more than one student. This map is useful for finding mathematical data such as the mean, median, and mode.

Range Graded Proportional Circle Map

The proportional circle map depicts the circles in relation to ranges of data, in various locations. The information is classified as spatially, it could also be equal quantiles, breaks, natural breaks, and minimum variance.
