I would like to know how can i make an animated ggplot map? I'm trying to build an COVID Visualization over-time.

To show you some example, here's a code of my own:

#Mortes

ggplot() +
  geom_sf(data=ontem, aes(fill=deaths), color="#FEBF57", size=.15, show.legend = TRUE) +
  labs(title = "Mortes por COVID",size=8) +
  scale_fill_distiller(palette = "BrBG",
                       name= "Mortes Confirmadas", limits=c(min(ontem$deaths),max(ontem$deaths)))+
  theme_void() + theme(plot.title = element_text(hjust = 0.5))

options(scipen=10000)

This code returns this map: enter image description here

I'd like to show the evolution of the COVID deaths over time. In the dataframe, there's a column named "date", which has the date time values like "2020-07-21".
