Directed Graph from Adjacency Matrix

I am new to Mathematica.  Here is my question.  How would I get a 
directed graph from an adjacency matrix?  For instance, the 3x3 matrix 
{{0,1,0},{0,0,1},{1,0,0}} defines a directed 3-cycle, but when I try to 
turn it into a graph using FromAdjacencyMatrix, Mathematica returns a 
graph with only two edges.

Thank you.
