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

该 issue 提到了 Plot、plot.show()、Traces 和 plot_configs，但没有指出文件或测试。首先定位这些入口点，并使用所描述的线程 workaround 重现并发创建和显示 plot；完整的解决方案需要一种已确定且可测试的方式，以处理跨线程和多种配置的 plot。
