Hi Hostilio

Thanks for using Syncfusion products.

Please note that currently we don’t have Ko and angular support for collection of nodes and connectors properties. We have already logged a feature with “Ko and Angular support for collection of nodes and connectors” and it will be implemented in our upcoming release volume 4 2014, which is scheduled to release in the end of December. Please refer the incident 132167  for more details regarding this feature.

Please let me know if any concerns.

Was this ever implemented?  Are there any examples using AngularJs?

Hi Hostilio

We have already implemented this feature “Ko and Angular support for collection of nodes and connectors”. However we have created a simple sample in which we can add the node and connector at run time through angular binding. We have provided the sample in JSPlayground which is available in the below link. Also please refer the below video for your reference.

Thanks again.  The attached JSPlayground link helped clear up my understanding.

I have adding/removing nodes working in my project using AngularJs.
