I recently created a mindmap/flowchart of GTD with MindManager. It's a large map, but I found it helpful to have a bird's eye view of the entire system. In case anyone finds it helpful, the link is here. Comments are welcome.
(Please note that these are not my ideas, this mindmap is unofficial and is provided for educational purposes only, and I encourage you to visit Davidco.com and/or buy Getting Things Done.)
