I've saw many "Flags Map" on this site, and on other sites, like this : http://althistory.wikia.com/wiki/File:Flag_map_post_ww2.png

Or like this : http://s23.postimg.org/ejh3x3wsb/Flag_Map_1800.png

But I don't know how to make them, and what software I should use, I'm just wondering how this can be done. Thank you.
