Hi Paulo, The Google Maps service that is used by the map-related charts in Google Charts is now limited in a couple ways. Without the use of the mapsApiKey, you can still use the maps in the same way, and it remains free, but this usage will be combined with everyone else in the world using it this way, and all will be 'throttled' after some point, meaning that more usage will slow down the responses or possibly be blocked until usage thins out. I'm not sure of the details on this throttling process (e.g. what rate per day is permitted), but that is the effect.
If you do set up your own mapsApiKey, then you will be unconstrained by the above public limits, but there will still be throttling limits based on the usage pattern of your users. I don't know that paying for such a key could get you a higher limit (maybe so), but I believe getting a free key will serve most usage just fine. The limitations are only for use of the geocoding aspect of maps. The map data itself is pregenerated and served by Google Charts.
