Found this site where you can check boxes for countries where you've been and draws a map for you. It doesn't mean that you've seen the length and breadth of a country, though. Just being to a single city is enough to mark the whole country as 'visited'.
This is what my map looks like:
So far I've circumnavigated the world four times and the only two continents I haven't been to are Africa and Antarctica.
LOL, I will lose this one. I have never been outside the US. I have never even owned a passport. When I was in San Diego, I thought about stepping across the border into Mexico, but I never found time to fit it in. (I believe that a passport was not needed to do that at the time.) But I have been around the US quite a bit. It's a large country.
I have been just to one country outside my home country 
Cool idea blowtorch! Hope to see you in Thailand, your first visit here, I see.
I'm not much of a globe-trotter. I live in the US. I've been to Panama and Romania. I had about a 2 hour layover in Germany on the way to Romania. In Romania, I actually went to the real Dracula's (Vlad Tepes) castle.
Here's the glimps into my travel:
Obviously I don't enjoy travelling.
I used to travel a lot, up to nine months of each year, but not so much anymore. Quite a few of the places on this map I have been in only a day or two.
Sounds the same as me. I've been to almost every state but never out of the country. Like you, I was in San Diego but I did take one step across the border just so I could say I was in there. 
I owned a passport at the time because co-workers said it would be good to own one in the off-chance I would get sent overseas for work. Never did though.
For me:
I love travelling especially around Spain ,Ireland and USA so ...many beautiful places to see .
In the states:
Only took about 10 minutes to figure out how to get the picture.

I LOVE MY COUNTRY!!!
I like the way I get all of Canada from just having spent a long weekend in Toronto -- that's what I call a return on investment.
What might be interesting would be to make a map of the countries you have not visited but might like to, for example
Impressive!! How many countries total is that??
