Looking at coming up with some new concepts for decisions trees that can be used/adapted for both mobile and desktop views of a web application. Just wondering if we have evolved from the classic decision tree diagrams to something more practical and user friendly for the web?
Has anyone seen good examples of innovative approaches to designing this type of interaction, especially for deep decision trees, that allow a user to track the decision making process (hopefully not a series of radio button selections in collapsible UI components)?
The type of decision tree structure that I am designing for is generally YES/NO decisions, but occasionally there are some selections from 3-4 items. Each branch generally goes into at least 3-4 steps further before ending. I don't necessarily think it is important to show the user the whole path at any given time, but it is ideal for them to be able to see at a glance where they have come from and allow them to step back easily.
I have tried to do some searches on Google Images under "nodal material editor" and "interactive decision tree" and some examples of what I am looking for might be similar to some mindmapping tools or these examples:
