Implementation of ggalt::geom_encircle()

Good evening,

• I will say first thank for the awesome packages and more for the R community, this is just awesome !

• I have found a topic yet not covered by the plotly package. You will find bellow a reprex with the error message.

library(magrittr)
library(ggplot2)
gp <- iris %>% 
        ggplot(. , aes(x = Sepal.Length, y = Sepal.Width, colour = Species)) +
        geom_point() +
        ggalt::geom_encircle()
plotly::ggplotly(gp)

Warning messages:
1: In geom2trace.default(dots[[1L]][[3L]], dots[[2L]][[1L]], dots[[3L]][[1L]]) :
  geom_GeomEncircle() has yet to be implemented in plotly.
  If you'd like to see this geom implemented,
  Please open an issue with your example code at

まず、提供された R reprex を ggplot2、ggalt::geom_encircle()、plotly::ggplotly() とともに実行し、その後、warning に示されている geom2trace.default のパスを調べます。geom_GeomEncircle() が未実装であるという警告が例から表示されなくなり、囲まれたプロットが plotly を通じてレンダリングされれば完了です。
