This adds the fields to your result but it does not filter or aggregate per continent.

What we are looking for is something that in the end would have one object per continent year and age, lucky for us, the dataset already have those information, At this point you will need to look into the dataset itself to find if you have some data about continents instead of countries (maybe search for Europe and see what it result on)

I would advise, since the data is stored in mongodb to use the power from mongodb and javascript to figure our what the Country field can be and maybe search into it what could be used to have the data per continents
