Graphic representation of binary tree with branch values

This is a painfully simple question, but would it be possible for someone to provide me with graphic representations of t1 and t2 in the example below?

Thank you!

(*A representation of a binary tree, where both nodes and branches contain values*)

type 'a nodetree = Node of 'a |Branch of ('a nodetree * 'a * 'a nodetree);;

let t1= Branch(Branch(Node 1,2,Node 3),4,Node 5);; 
let t2= Branch(Node 1,2,Branch(Node 3,4,Node 5));;
