## Croatian Destinations
Write an R script that creates a map of Croatia. On
the map, mark 3 places you would like to visit.
Use the rworldmap library. Use Geonames to obtain
coordinates: https://www.geonames.org


```{r croatia}
library(rworldmap)
world <- getMap(resolution = "low")
plot(world, xlim = c(20, 30), ylim = c(35, 71)
     , asp = 1
     , col = "white"
     ,bg = "lightblue",        # background (sea) color
)
#points(airports$lon, airports$lat, col = "red", cex = .6)
```
