 This histogram shows the number of topics having some specific number of associations. Association refers here not only associations but also class-instance relations between topics. The leftmost bar represents topics with no associations, the one after that topics with one association and so on. The green highlighted bar represents the average number of associations each topic has and the red highlight can be moved using the mouse to see the exact values of each bar. In this case the red bar represents topics with 13 associations and the top part of the window tells us that there are 28 of such topics.
-The leftmost bar, representing number of topics without connections can be used to determine the number of totally separate topics in topic map i.e. topics without associations, instances or types.
+The leftmost bar, representing number of topics without connections can be used to determine the number of totally separate topics in topic map i.e. topics without associations, instances or types. Typically the number of totally separated topics in topic map is rather small containing perhaps occurrence and association types and roles. Thus, large number of totally separate topics usually indicate the topic map contains forgotten topics.

 The formula used to calculate connection count depends on options given to Wandora at count startup. Possible options include:
