Usecase: Given i make a map scoped on Africa And i do some click event like """

 done: function(datamap) {
        datamap.svg.selectAll('.datamaps-subunit').on('click', function(geography) {
            // change color using geography.id
        });
    }

""" Then i give the following message error """ Uncaught SyntaxError: An invalid or illegal string was specified. """

the id is the only negative number that i found

geometry: Object
id: "-99"
properties: Object

is it normal ?

All regions that are disputed in every map i encountered (this, jQvmap etc) give a negative value to them. Not sure why, but you can modify the source yourself if you need to have it..
