geom_GeomAlluvium() has yet to be implemented in plotly

[nguyenkhoa0209]

I currently used the package ggalluvial to create alluvial diagram.
And It would be nice to see geom_GeomAlluvium() supported by ggplotly().
Here is an example that I used the code pulished on https://cran.r-project.org/web/packages/ggalluvial/vignettes/ggalluvial.html

library(plotly)
library(ggalluvial)

p = ggplot(as.data.frame(Titanic),
       aes(y = Freq,
           axis1 = Survived, axis2 = Sex, axis3 = Class)) +
  geom_alluvium(aes(fill = Class),
                width = 0, knot.pos = 0, reverse = FALSE) +
  guides(fill = FALSE) +
  geom_stratum(width = 1/8, reverse = FALSE) +
  geom_text(stat = "stratum", label.strata = TRUE, reverse = FALSE) +
  scale_x_continuous(breaks = 1:3, labels = c("Survived", "Sex", "Class")) +
  coord_flip() +
  ggtitle("Titanic survival by class and sex")

ggplotly(p)

Thanks for the example code, I've added to the list in #566

I implemented a to_basic method for both geom_stratum and geom_alluvium. Will be running tests and adding a pr in the next hours
