Chordal graph and its clique tree A graph $G$ is chordal if it is the intersection graph of subtrees of a tree $T$. In particular $T$ can be chosen such that each node of $T$ corresponds to a maximal clique of $G$ and the subtrees $T_v$ consist of precisely those maximal cliques in $G$ that contain $v$. $T$ is then called the clique tree of $G$. 

Now my question is the following. 


  Is any tree can be represented as a clique tree of some chordal graph?


Any counter example or hint of proof is welcome.
Chordal graphs can be defined as intersection graph of subtrees of any tree.  So the answer to your decision question is trivially YES.  On the construction side, for each subtree $T_v$ of bags (it's convenient and conventional to call the nodes of the tree as bags), you'll have a unique new vertex $v$, which is put into all bags of the $T_v$.
