You know, despite being quite different than what you described, what comes close for me in concept is the Spyder IDE. They have pretty reasonable data visualization tools when you go to inspect variables. I find it really nice work in. It lets me do the real visualization and interplay between variables in code or in my head and just quickly inspect tables/vectors/rasters to sanity check as I work in real time.

What's missing is the ability to then manipulate those tables and have it backfeed into the code, but I think that honestly you could again get close to that with some basic right-click>generate new column> type in python expression > translate to input into interpreter type of workflow.

I also know there are some python based excel type programs.

Despite how many flaws the language itself has, the MATLAB IDE is probably as good at this as Spyder, if not actually better.
