plotly takes twice as long as ggplot2 at 30 seconds

[bugzpodder]

library(ggplot2)
ggplot(df, aes(x=activity_mean, y=concentration)) + geom_point()

takes 15 seconds. Change ggplot2 to library(plotly) takes 30 seconds to run. Cache is enabled and plotly is loaded via disk cache

Similarly to #306, I believe this is a consequence of package loading -- the plotly package depends on more packages (70) than ggplot2 (28).

Nevertheless, this should be improved in the next version of webR. The latest development build of webR at https://webr.r-wasm.org/latest/ takes about 2.5s to load plotly (from disk cache) for me now.
