I think its worth posting a backlink to this thread (among many) exploring these ideas, although Cassady’s idea merely to graph the references to other documents is interesting and may provide less visual clutter.

The Hanah Jacobs paper referenced in that thread is perhaps the most useful example of different kinds of visualisation I have seen
Personally after spending many hours with graphviz I haven’t managed a result which is actually useful, as opposed to just looking pretty. Search this forum for what other people have achieved with graphviz and python before to map the connections between tags.
Simply producing a table of linked documents might still be useful. Its something I explored in a more limited fashion in this thread - [url]Export an index of annotations to a numbers spreadsheet]
The problem I can see from a scripting perspective with Cassady’s idea is that its quite hard to obtain a clean list of all urls in a rich text document with the current DT applescript. It can be done but its very slow as you have to parse every word of the text and filter out duplicates. Its probably a task better given to an external script.
