The function geoNaturalEarth() is used to return the Natural Earth projection.
Syntax :
d3.geoNaturalEarth()
Parameters: This method does not accept any parameters.
Return Value: This method creates and returns geoNaturalEarth() projection from given JSON data.
Example 1: The following example creates geoNaturalEarth() projection of the world with the center at (0, 0) and no rotation.
