I am not sure whether diagram is your model here, try with your Model, because i don't see you are getting a document via find or findOne method on which you can apply remove method.

Model.remove({ _id: id}, function(err){});

Or you can also find and remove:

Model.findOne({_id: id}, function (error, daigram){
   daigram.remove();
});

You can also use the latest version:

MyModel.findOneAndRemove({_id: id}, function(err){...});
