Figure label auto-positioning

This is a customer requested feature. In both R and MatPlotLib there are extensions which allow figure labels to auto-position for readability by preventing overlap. See gif below.

It is possible to acheive this effect in MatPlotLib and R

At least one customer has requested, and it's a feature which is not possible for a client to easily implement by themeselves. Current label positioning options are not dynamic in this way, and as a result we don't see a lot of client figures using labels, especially when there are more than a few points on the figure. Most clients default to hover, but that isn't viable for everyone, especially in settings where apps are being viewed on different devices. It's potentially also an accessibility improvement.
