I'm a long org-mode user and I absolutely love it. During the years I've been using org, nothing else came close to being so simple and so powerful as org - and I a lot tried different productivity apps.

One thing that would nicely complement org, in my opinion, would be a visualization mode for its buffers. Right now I sometimes use Freeplane*[0] to draft/brainstorm complex ideas or problems/solutions and then attach it to an org item and write more specific action items there.

It'd be nice to have everything in a Freemind map, if needed. What I'm proposing is a way to visualize org buffers in Freeplane and vice-versa. 

It could also be a script that uses something like graphviz*[1] to create a graph of one or more org buffers, like Sasha Chua did here: http://pages.sachachua.com/evil-plans/, although I prefer using Freeplane since it allows me to edit the org file as a mind-map, visually, if I want.

I think a script to automatically transform the Freeplane XML to org and vice-versa wouldn't be too hard to come up with. The graphviz solution is also interesting and Sasha already provides the snippets.

Are any other people out there that are already doing something similar to what I described above? Maybe we could share some ideas on how to tackle this feature or if it'd be worth adding it into the org core ;)

Cheers!
