I recently needed to create a view of type "Term" that displayed taxonomy terms and their description for a certain vocabulary.
The setup for that was quite simple
- Create a view of type "Term"
- Add an argument of Vocabulary ID
- Add a field of "Term Name" and another of "Term Description"
- Add a filter of "Vocabulary" and select the vocabularies you want to restrict to
This gives a nice simple view of all terms belonging to a single vocabulary when the vocabulary id is passed as an argument.
