I'm not sure which information you are trying to visualize, but perhaps the following information will provide an answer:
In SAS Enterprise Miner 5.x, a separate application named the Tree Desktop Application (or TDA) was used for the interactive tree functionality. When you close the TDA to exit the interactive utility, the relevant information from the current model (partial or completed) is passed to the Decision Tree node. You can then view the results or rerun the Decision Tree. In SAS Enterprise Miner 6.x and later, the interactive capabilities were natively inside of SAS Enterprise Miner.
I hope this helps!
