Cities with the same name using Geocharts

Question

I’m doing a project, using Geocharts, as I’m working all the municipalities throughout Brazil, there are some cities with the same name, when I show these cities, they appear in the wrong state, has anyone ever been through this problem? In the following photo, I’m searching all the cities of the state of Pernambuco, and I checked the cities that are in another state, are those that have the same name, example in RS.

Answer 1

Solved, I used a Concat(municipios.nome,' ,) in the PHP file that generated the json. Geocharts recognizes cities with the same name, saying what state it is from. Example Maceió AL
