request to implement geom_GeomPointGGtree() in plotly

[schultzm]

Hi,

When trying to run:

t <- ggtree(tre) %<+% blocks +geom_tippoint(aes(colour=gene))
ggplotly(t)

I get the message

Warning messages:
1: In geom2trace.default(dots[[1L]][[1L]], dots[[2L]][[1L]], dots[[3L]][[1L]]) :
  geom_GeomPointGGtree() 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
  https://github.com/ropensci/plotly/issues

Thanks,

Mark
