[R] Need panel plots by each state, comprising three columns in R

[Ranjeet Kumar Jha]

Hello,

I need to draw a panel plot by each importing the attached csv data (sample
panel plot attached as well). Each state should contain three columns-  wt,
avg, and observed, may be represented as legend or x-axis, and y-axis
should show values.
I tried doing it in ggplot in R but couldn't succeed.
Please help plotting this panel plot.

Thanks,
Ranjeet
