Simple Sigma.js AngularJs Directive: Since I did not find any angularjs directive for angularjs I created a little simple of my own. This is by no means a ready-for-all solutions, but all the features I needed at the time; it is easily extended to your needs and maybe sometimes somebody will do a full-blown directive for sigma.js Tested: angular…
