OData binding in Network Graph

Hello,

I'm a newbie to UI5. I'm trying to do a POC using Network Graph controller. Here are the details about the issue:

I'm working on creating an Org chart. It works perfectly using JSON model. I have created a table for Employees and exposed it via OData. zemp-table.png

I'm missing out something during OData binding. Please provide your suggestions. data-binding.png

Also, the URL works fine when used in browser. But while running the application, it gives error. browser-error.png

Thanks in advance.

Regards,
Sri.
