How to change the map's language?

You can change all the country names on the world map. You just need to open the online customization tool and replace the English names with the language names you want.

You can also do this dynamically. Here, you can download JavaScript files for the top languages in the world:

Then, you can simply copy and paste the language.js file and use it on your webpage. Here's an example with "Polish" applied to the World Map:
