Diagram - Editable

Connections can be created and edited on the fly using drag and drop. In this example, computers are sources whereas servers are the targets. Once a connection is created, removed or changed using drag and drop, diagram makes an ajax request to save changes in the backend model. Additionally, optional ajax events are provided as callbacks.
