如何知道图形API响应中的数据类型？

Question

I'm beginner of graph API. For my Application, I have to use many graph API at the same time.

My question is... how can I know the response's data type? => How can I know the response that it is the friends data?

ex) for friend data. In response data, I can't find the data name for friend.(== like friend tag name in XML response)

• request Graph URL = https://graph.facebook.com/100000726819009/friends

• response data in graph API for friends
