Use a cartogram when you need to represent an area in the context of the value a variable associated with it holds, making it useful as an isodemographic map. What are advantages and disadvantages of maps? A common use of distance cartograms is to show the relative travel times and directions from vertices in a network. [5] Both maps showed a similar outline of the German Empire, with one subdivided into constituencies to scale, and the other distorting the constituencies by area. [39] This program also provides an optimization to the original Dougenik rubber-sheet algorithm.
