Can anyone help me i am new to d3 and did not know how to extract specifc data from csv file as i am trying if(importer1===Panama) {draw chords....

}

but its not working. thanks in advance

Solution

  • Simple use filters as shown below this will filter record for Panama

     d3.csv('trade.csv', function (error, data) {
        var data = data.filter(function(d){ return d.importer1 == "Panama"});
        var mpr = chordMpr(data);

    Working code here

    Hope this helps!
