Angular.js自定义指令和d3.js

Question

Its not that difficult to get an angular.js directive combined with d3 to work(thanks to stackoverflow). But i cant get those arrows to work. The code is taken from an example of M.Bostock. (Original Example) I just wanted to put it in a directive and failed. It renders fine when i inspect the DOM i can see the arrows but they wont show up. Does anyone have a clue ?

Directive

angular.module('test').directive('myNodes', ['$compile', function ($compile) {
    return {
        restrict: 'A',
        link: function(scope, element, attrs) {

I created a plnkr based on what you provided and it works OK - are your references to AngularJS and D3 OK?
