A circle packing visualization showing all databases and their sets of types sized according to their volumes (# of entries).
As in other visualizations that involve all Encyclopedia databases, the graphics is dominated by the World Problems and Global Strategies. The databases of Human Values and Human Development are both about ten times smaller. The cluster representing Metaphors and Patterns is the smallest one. Note that the database of Integrative Concepts does not show at all here because it does not use any type categorization.
