This is less interesting than some people but probably more interesting than most. Unfortunately, Barbados doesn't show up very well. Aside from Kazakstan, which was just a 10-minute drive-through, I've spent more time in any of these than I have in most of the states on my U.S. map. Barbados and Ireland were a week each, Germany and Uzbekistan were something like 6-7 weeks each, and Canada probably adds up to at least a couple weeks when you combine the various visits. The U.S. is going on three decades. For obvious reasons the 5-6 other international visits I had weren't on the map (4-5 sovereign Native American nations and the United Nations building in New York City).
Update: I've added a new map, since the old one stopped working, and I've updated the link to the Visited States post, since that one got deleted accidentally during a change in location for this blog.
