Box plot
Boxplots are used to display differences in data without making any assumptions of statistical distribution. In this box plot the speed of light in various experiments are being analyzed.
Histogram
A histogram "is a graphical representation showing a visual impression of the distribution of data". In this histogram we have arrivals per minute on the x-axis and then the frequency of the arrivals on the y-axis.

Triangular plot
Triangle plots are used to represent three different variables. In this case we are looking at oxygen, nitrogen, and methane.
Windrose
Windrose's look very similar to the compass rose which we navigate North, South, East, and West with. Using a wind rose meteorologists can measure the wind direction in a given area.
Climograph
Climographs show the basic climate parameters, like temperature and precipitation. On this chart temperature is on the right side and the months are on the x-axis. Judging by the chart June through September receive the heaviest amount of precipitation.
Population profile
Population profiles are charts that represent people as a function of thier age. On the chart we have to two quadrants separated between males on the left and females on the right. On this chart the origin is in the middle with the numbers increasing away from it.
Scatterplot
http://en.wikipedia.org/wiki/Scatter_plot
Scatterplots are used to display two or more sets of data using cartesian points. Correlations are formed when you can see a pattern between the points. This particular scatterplot measures input and quality.

Unclassed choropleth maps
http://candacesmaps.blogspot.com/2010/12/unclassed-choropleth-maps.html
This map is one of the most interesting maps I have come across. Its interesting due to the fact that all the talk about the 2012 presidential election has passed. In this map you can see the percent of democrats given by the blue and republicans given by the red and how their colors have blended into a purple like color due to a blended mixture of the two parties.

Classed choropleth maps
These maps are used to show data through color shading which is explained in the legend or key to the left hand side of the map. In this case we have the state of Florida, hispanic persons are represented by the shading. The dark green shows a heavier population of latinos.
Range graded proportional circle map
https://www.e-education.psu.edu/natureofgeoinfo/book/export/html/1553
This map is similar to the Continuously variable proportional circle map in the fact that it uses circles to represent data although in this map there is more than just one piece of data at work. This map shows the amount of cartography courses in The United States, per state as well as the relative importance of the courses.

Cartographic animation
http://images.apple.com/downloads/dashboard/information/images/radarinmotion_20070608173303.jpg
Cartographic animations show animations such as cloud formations, hurricanes, wind movement, and many more that are helpful to people many of which they use on weather channels. It is easier to understand what large weather fronts are doing when you can visualize through the help of satellites.
Statistical Map
http://personalpages.manchester.ac.uk/staff/m.dodge/cybergeography/atlas/census.html
Statistical maps are used to show data represented by color or percentages. In this map International connectivity is shown, the areas in purple are those areas with internet and the yellow represents areas without internet. It is crazy to see how much of our globe actually has internet.

Proportional circle maps
I remember a map similar to this on the second test and proportional circle maps are used to display information like population based on the size of the circle on the map. For instance the largest dot is on california because it has the largest population of mexicans, and the smallest(shown on this map) is North Dakota because no mexicans apparently live there.
Chloropleth Map
http://www.google.com/
For my Chloropleth map I chose this map of California which depicts black Condo owners. I'm not entirely sure why this map was constructed but perhaps it was made for real estate purposes.

Dot Distribution Map
http://www.google.com
This is a dot distribution map which shows population in the United States 1 dot represents one hundred thousand people as as you can se places like California and the upper north east are the most densely populated.

Hypsometric maps
http://www.google.com/
This Hysometric map is of the small island of borneo the contour of Borneo with the green color being closer to sea level and then gaining elevation as you move to the yellow portions of the map. These maps are useful when you need to know the terrain so you dont go hiking and expect to be on flat surface and then find a huge mountain in front of you.

Cadastral Map
http://elcoco.co/new-cadastral-maps-provide-better-security-for-property-in-costa-rica/
This is a Cadastral map of some land in Costa Rica. Cadastral maps are used to show property ownership. In this map the use of a cadastral map is important because it displays who owns what and all the property lines you can see the individual properties in the pink and then in yellow you can see other properties on the outskirts of the town.

Thematic Map
http://soils.usda.gov/use/thematic/dv_soilmap_high.html
This map seemed like a good representation of a Thematic Map. It was hard to find a map on Google that hadn't already been taken by someone else's blog but when i found this one I thought it was cool enough to use. This map shows the United States of America and the drought spots throughout the county in red. Thematic maps are good to display information like this another good use is a map of population and anythings that is distributed throughout an area.

Topographic Map of Mars
http://sos.noaa.gov/Datasets/dataset.php?id=227
Considering all the talk in the news lately about mars I decided for my topographic Map I would do one of Mars. If you're unfamiliar with whats been going on about mars we have recently landed a rover o it's surface and much talk about colonizing mars has been in the media. This is a good display of topography because you can see the contours that are on the planet mars some of its largest features like its enormous volcano; Olympus Mons.

Although this map is harder to see I thought it was an interesting planimetric Map because I found it in florida states index. After looking it over for a few minutes its hard to make out the names and I cant really tell exactly which part of campus it is. This is a good description of a planimetric map because it doesnt convey land contour only the horizontal/vertical lines.
Mental Maps
http://www.google.com
The type of map that I chosen to discuss this time in a picture I found off of google of someone's attempt of a mental map. I though this was a good choice for my description of a mental map because I remember back when I was younger trying to draw maps of my neighborhood based soley on memory of the area. Mental maps are good for basic streets and houses like this one here but would be hard for most people to make mental maps of very complex areas like cities or large scale items.

Doppler Radar of A Hurricane Over Florida
http://deadlystorms.com/storms/2004/2004%20charley/videos.htm
What you are looking at is a map of Florida as a hurricane approaching from the Gulf of Mexico hits the west coast. If it wasn't for maps like this people would have no idea of the approaching storm. These maps are used by all weather forecasters to show what the human eye can not see and to predict potentially disastrous weather in the future. Doppler radars come from satellite images and usually show a certain time frame so you can see the direction of a storm front. Doppler radars are also very important for aviation so that pilots can see what kind of skies they are heading into.
Doppler radars work by sending microwave signals through space and waiting for a returning frequency to analyze the depth of the weather. It is a very important tool and these maps will continue to save lives and help people for many years to come.
