This is great advice. But it you (or your boss) insists on pie charts,
then you should provide us with a reproducible example that
illustrates your problem.

dat <- read.table(text="Product    predicted_MarketShare
Predicted_MS_Percentage
A                    2.827450e-02                             2.8
B                    4.716403e-06                             0.0
C                    1.741686e-01                             17.4
D                   1.716303e-04                             0.0",
                  header=TRUE)

pie(dat[[2]], labels=dat[[1]])

Does not give overlapping labels, so I don't yet have an example of
the problem you are trying to solve.

Best,
