You should check out https://github.com/IGITUGraz/live-plotter https://github.com/IGITUGraz/live-plotter (I am the author of the package) It is designed exactly for this use-case -- visualizing results of an ongoing simulation. It does best effort plotting, but doesn't block computation for plotting. I would be happy to receive feedback on the package.
