Visualizing each explanatory variable
Being able to see the predictions made by a model makes it easier to understand. In the case where there is only one explanatory variable, ggplot lets you do this without any manual calculation or messing about.
To visualize the relationship between a numeric explanatory variable and the numeric response, you can draw a scatter plot with a linear trend line.
To visualize the relationship between a categorical explanatory variable and the numeric response, you can draw a box plot.
