11.47 Line Chart Skewed Distributions

ds %>%
  filter(rainfall != 0) %>%
  ggplot(aes(x=rainfall)) +
  geom_density() +
  scale_y_continuous(labels=comma) +
  theme(legend.position="none")

The plot informs us about the skewed nature of the amount of rainfall recorded for any one day, but we lose a lot of resolution at the low end.

Note that we use a subset of the dataset to include only those observations of rainfall (i.e., where the rainfall is non-zero). Otherwise a warning will note many rows contain non-finite values in calculating the density statistic.
