  We define a canonical relative commutant planar algebra from a strongly
Markov inclusion of finite von Neumann algebras. In the case of a connected
unital inclusion of finite dimensional C*-algebras with the Markov trace, we
show this planar algebra is isomorphic to the bipartite graph planar algebra of
the Bratteli diagram of the inclusion. Finally, we show that a finite depth
subfactor planar algebra is a planar subalgebra of the bipartite graph planar
algebra of its principal graph.
