A box and whisker plot provides a visual representation of numerical data, and makes it easy to determine outliers in the data. This plot shows the page count of Wired Magazine in relation to the December page count, which is the line horizontal line through the center. By noting how far removed (or not removed) from the center line the box is, the viewer can determine how many more (or less) pages were in each issue. As can be seen from this plot, every other issue had less pages than the December issue, with November being the closest contender in page number.  

Flow Map

Flow Map: a map that shows, by proportionally varying width of lines, the amount of traffic or flow within the network.

As can be seen from the map, the amount of asylum seekers coming to the USA can be compared to other continents by comparing the width of the arrows. South America and the Caribbean are the smallest, followed by Europe, and Asia and Africa seem to be about equal. As an example of a flow map, this map is very functional, but as a stand-alone resource it is not- what years does it show? What kind of asylum seekers does it show- just those from war, or from other issues as well? Can the width of the arrows be directly related to a number?
