Add labels to points to aid data exploration

I posted this to
but it was suggested that the mailing list was a better place.

I am plotting a simple graph with many points. I would like to explore
the data by clicking on some of them to see what their labels are
(much as I can already in R). I don't want to see all the labels at
once. Currently the only solution I found was mpldatacursor. Is this
feature something interesting to matplotlib developers or even being
currently worked on?
