Typo in graph.md where showing the result of followers djw

[davidAg9]

I might be wrong but the result from the query of the followers of djw which present the result as follows : $ db.followers.find({_f : "djw"}, {_id : 0, _t : 1}) {"_t" : "jsr" } {"_t" : "ian" }

should have been : $ db.followers.find({_f : "djw"}, {_id : 0, _t : 1}) {"_t" : "jsr" } {"_t" : "pete" }

or otherwise, I do not understand the implementation very well and will close this issue ... I am very new to MongoDB and have used it for only 1 year and a half now.

and I think for a better explanation it will be nice to know the meaning of _f & _t ( i am however aware of its indexing purpose which was already explained) as I am reading as from and to
