I am getting undefined in printing obj to the console. How to access the answer outside the function??
var obj;
d3.json("country.json",function(error,answer){
obj = answer;
});
console.log(obj);

1`d3.json` is asynchronous - you can access and use the value inside that callback – Jaromanda X Feb 03 '20 at 10:33

the code in the callback (`obj = answer;`) is called asyncrhonously - you can't access it (reliably) outside that asynchronous callback – Jaromanda X Feb 04 '20 at 07:39
