Interesting, it's something to think on. Creating such visualisations manually may be prohibitively complicated, but I can imagine some cases where they can be derived automatically (e.g., for compiler passes, an example IR can be displayed before and after).

You might also want to check out live programming, which focuses on interactive debugging rather than the improvised problem solving (as well as live performance) of live coding. Once you get to live programming, techniques like time travel become viable, which otherwise don't make much sense with live coding. You can then better tackle traditional programming problems with better live feedback.
