Information can be represented in many ways, and this applet allows the
user to represent data about the states using colors. The state with the
highest data value is darkest; other states are shaded proportionally.
Investigate any of the data provided—or enter data of your own!
Select the Data Set for Land Area. As
expected, the states that look bigger are a darker color, because larger states
have more area. (Alaska is not drawn to scale, so even though it does not appear
to be the largest state, it is the darkest. Indeed, it has almost three times
the area of the second largest state, Texas.)
An attribute that is not obvious by visual inspection is the state
population. Choose Population from the Data Sets menu. Do the largest
states have the largest populations?
Now, combine these two elements by opening the Data Set for Population
Density. You'll notice that most of the states appear in a very light shade.
