Add pointplot to the possible plots that can use the annotations

[robertour]

I am not sure if there are internal differences, but I often I use pointplot (instead of barplots) because they are less cluttered,

(pointplot might not be the right plot to use, but it is inspired in the seaborn gallery: https://seaborn.pydata.org/examples/jitter_stripplot.html. In any case, feel free to point out a better alternative)

Is it possible to add pointplot to the list of supported plots?
