I have a request. Somebody needs to make matplotlib, but with a C API and lots of language bindings instead of only a python API. For example when I'm writing rust, my best option is to use a Python interop library that calls matplotlib...
I think having a built-in web server via a visualization library that shows the graphs etc in a browser is 'optimal' -- because then, the whole crap of e.g. dealing with Tkinter to make your windows goes away. You achieve OS independence, and could even use lynx for text-only.
The Python visualization space is vast. I believe 'something better' will shake out in the next few years.
I'd only touch Rust (or C/C++) when I need to implement some fast numerical computation that does not already exist in Numpy or Tensorflow, but still call it from Python.
If the thing could have been written in rust in the first place, tons of time would have been saved on trying to optimize python, waiting for simulations to complete before (and to a lesser extent after) I ported a portion of it to rust. Dealing with language interop and build systems.
The main reason I can't suggest that for future similar problems to the person who I did this for is because of the lack of libraries like plotting (plotting is by far the most important one, numpy is second but rust comes a lot closer in that regard).
