How do you show multiple plots in threads concurrently?

TLDR: Ultimately, my question is, would it be possible to adapt the Plot type to be Send so we could more easily show multiple plots at once? (or is there another way to achieve that? should we serialize the plot?)

I love Plotly and use it a lot, one thing I noticed is plot.show() is blocking, and the natural way to show multiple plots at once would be to send them to threads, but something about the Traces prevents us from being able to show multiple plots at the same time:

This is workaroundable if we create threads to both create the plot and show it, like this:

but then we can't return the plots made in those threads to our main thread:

also, this approach might trip up if we want to create and show multiple different kinds of plots from multiple different kinds of plot_configs, although i guess we could use an enum like this:

just curious how y'all handle this, right now I'm doing the workaround but thought it would be cool if we could just make a bunch of plots and send em around without issues

The issue names Plot, plot.show(), Traces, and plot_configs but no files or tests. Start by locating those entry points and reproducing concurrent plot creation and display with the described thread workaround; a complete solution would need a decided, testable way to handle plots across threads and multiple configurations.
