        citypos <- incity %>% select(city,lat,lng,population) %>% filter(population > 1000000)
        seemap <- citypos %>% leaflet() %>% addTiles() %>% addCircles(weight = 1, radius = sqrt(citypos$population)* 30, popup = as.character(citypos$population/1000000))

## Assuming "lng" and "lat" are longitude and latitude, respectively
