Another imperfection to this otherwise interesting tool: it is hard if not impossible to click on small countries or islands. Good luck if you want to know who goes to Guadeloupe. Pascali Islands are hidden by the legend if I'm not mistaking. This is inherent to any "click a country on the world map" tool. A complex and not perfect way to fix it would be to allow zooming, but here I would add a drop-down with a list of countries.
