This explanation in the js tutorial sounds good, but we made some change when were writing py docs https://plot.ly/python/pie-charts/#controlling-text-orientation-inside-pie-sectors, so we can leave it as is?

@Mahdis-z Thanks for pointing out the Python version of these docs. While I can see the direction you guys were trying to go in when writing it, I still feel like the explanation in the js docs is much more clear for users, especially for those who don't already know what "tangential" or "radial" mean. I believe that it should be the standard language we use to describe this attribute across the R, JS, and Python docs.

However, I'll defer to @nicolaskruchten's judgement on whether or not this should block this PR from being merged.
