Applying gravity to this map using the frequencies of the paths between the different sites leads to an interesting insight into the visiting behavior: there are only a few paths which the vistors follow. Starting at the main entrance (lower right) there is a large circle on the left, with very few central places in between, where visitors switch directions. The most central area is around the Kodiakbears, which is the main link to a smaller circle (upper right). This smaller circle is identical with the second area of the zoo cut off by the autobahn. The area itself is much smaller, because the locations in this area are more tightly interconnected.
