    connectorCollectionChange: connectorCollectionChange
});
 
function nodeCollectionChange(args) {
    var node = args.element;
    //customize the appearance of a node
    node.fillColor = "darkcyan";
    node.borderColor = "transparent";
    node.labels[0].Text = "New Node";
}
 
function connectorCollectionChange(args) {
