Poisson regression plotting
Using geom_smooth to plot data from a Poisson regression is similar to plotting a binomial.
However, you need to change the family argument in geom_smooth().
During this exercise, you will plot the number of cancer cells per cm\(^2\) and use a geom_smooth().
This is the same simulated dataset you saw in the video.
