// [ [x: 1, y: 1], [x: 2, y: 2], [x: 3, y: 3] ]

//We, however, are using 'year' as x and 'amount' as y.
//We also need to know which country belongs to each
//line, so we will build an array of objects that is
//structured like this:
/*

…
]

…

//Note that this is an array of objects. Each object
//contains two values, 'country' and 'GDP'.
//The 'GDP' value is itself an array, containing
//more objects, each one holding 'year' and 'amount' values.
//New array with all the years, for referencing later
