I'm experimenting with large datasets in mapdeck and it's amazingly smooth. Thanks for that! However, it seems that adding a tooltip to a large number of points really slows down the map rendering. RStudio becomes completly unreactive if N increases.
library(mapdeck)
N <- 2e4
data <- data.frame(
longitude = runif(N, -180, 180),
latitude = runif(N, -180, 180),
tooltip = sample(LETTERS, N, replace = TRUE)
)
system.time(
mapdeck() %>%
add_scatterplot(
data = data,
lon = "longitude",
lat = "latitude",
fill_colour = "tooltip"
)
)
#> user system elapsed
#> 0.077 0.012 0.090
system.time(
mapdeck() %>%
add_scatterplot(
data = data,
lon = "longitude",
lat = "latitude",
fill_colour = "tooltip",
tooltip = "tooltip"
)
)
#> user system elapsed
#> 3.676 0.468 4.145

I experimented a bit and apparently time is growing exponentially.
