 `{incidence2}` produces basic plots for epicurves, but additional work is required to create well-annotated graphs. However, using the `{ggplot2}` package, you can generate more sophisticated and better-annotated epicurves.
-`{ggplot2}` is a comprehensive package with many functionalities, but we will focus on three key elements essential for producing epicurves: histogram plots, scaling date axes and their labels, and general plot theme annotation.
