What Is An Example Of A Cartogram?
What is an example of a cartogram? An area cartogram is a map that alters an entire physical location by scaling a chosen economic, social, political, or environmental factor.

Why do Cartograms look like distorted maps?
Cartograms exaggerate the size of the geography proportional to the statistic being shown. Specifically, the variable substitutes land area or distance. But what they do is really distort our view of mapping by breaking the golden rule – sacrificing geometry to convey information.
How many types of Cartograms are there?
There are four main types of cartogram which each represent the mapped variable differently – non-contiguous, contiguous, graphical and gridded.
What do Cartograms preserve?
Cartogram maps retain a partially accurate relative location and relative space, but the actual area of the individual polygons features are overrepresented or underrepresented based on the assigned values.
What is a contiguous cartogram?
A cartogram is map where the geographic features are located and sized based on the intensity of variable. Contiguous cartograms, while distorting the geographic shape and size of individual polygon features, maintain spatial connectedness to neighboring polygons.

Why would you not use a cartogram?
When Not to Use a Cartogram
Maps depend on variation in scale to represent a large area and a cartogram is not a true representation of the real-world area and may give incomplete information. One of the disadvantages of the cartogram is that it inevitably changes the visual representation of geography.
What is qualitative map?

UX and Usability Testing
With all this opportunity to track where visitors are clicking and how far they're scrolling, it just makes sense to test UX and usability. It's time to do a little UX testing to see what's going on. Use heat maps and overlays to see where people are clicking — and where they're getting stuck.
