# Visualizing linear and logistic models

As with linear regressions, ggplot2 will draw model predictions for a logistic regression without you having to worry about the modeling code yourself. To see how the predictions differ for linear and logistic regressions, try drawing both trend lines side by side. Spoiler: you should see a linear (straight line) trend from the linear model, and a logistic (S-shaped) trend from the logistic model.

`churn`

is available and `ggplot2`

is loaded.
