Forum: Ruby on Rails Graph API

Can any body help me how can get the number of peoples likes my post by
using graph api along with the profile image of that person...

Well, what you ask is quiet big. I don't know how you will integrate 
graph
with how many people liked your site or blah blah. One short thing you 
can
do is to put a facebook like button  on your website.

If you are looking at graphs, you might check into this blog.
