{ggpolar} provides a very flexible way to create dots in coordinate system for event list and connect the dots with segments based on {ggplot2}.
You can install the released version of {ggpolar} from CRAN with:
install.packages("ggpolar")
You can install the development version of {ggpolar} from GitHub with:
remotes::install_github("ShixiangWang/polar")
