Feature request: notched box plots

[krassowski]

I searched thoroughly for such option, but found only this unanswered post on plotly community website: Add option notch to box plots.

Here is some short introduction: https://sites.google.com/site/davidsstatistics/home/notched-box-plots
Here is a reference for notches from MATLAB: https://www.mathworks.com/help/symbolic/mupad_ref/notched.html,
And here is a question from stackexchange to highlight how notches should be sometimes rendered "inside-out": https://stats.stackexchange.com/questions/151580/how-to-interpret-notched-box-plots

Is such an option in-scope of plotly?

Yes, definitely in scope. We may not get to it for a while but we'd happily review a PR to add it!

Here is an example baseline:
