@joyrex,

You can open bootstrap modal and pass the link attribute of respective datapoint clicked to modal by using click event handler of dataPoints as shown in below code snippet.

var link;
function onClick(e){
  link = e.dataPoint.link;
  $('#myModal').modal('show');
};

$('#myModal').on('shown.bs.modal', function (e) {
  $('#myModal').find('.modal-body').load(link)
});
$('#myModal').on('hidden.bs.modal', function (e) {
  $('#myModal').find('.modal-body').html('')
});

Please take a look at this JSFiddle for complete working code.
