geom_curve missing

[danielsjf]

geom_curve is missing from the geoms that can be automatically converted from ggplot2.
There have been issues around this in the past but those were closed: #555 .

Example:

library(tibble)
library(dplyr)
library(ggplot2)
library(ggplotly)

data_points <- tibble(Node = c(1,2,3), X = c(1,2,1.5), Y = c(4,5,6))
data_segments <- tibble(From = c(1,2,3), To = c(2,3,1), label = c('Line 1: 800', 'Line 2: 1600', 'Line 3: 400'))
data <- data_segments %>% 
  left_join(data_points %>% rename(From = Node, X_from = X, Y_from = Y)) %>% 
  left_join(data_points %>% rename(To = Node, X_to = X, Y_to = Y))

p <- ggplot(data) + 
  geom_point(aes(x = X_from, y = Y_from)) + 
  geom_curve(aes(x = X_from, y = Y_from, xend = X_to, yend = Y_to), curvature = 0.1)
p
ggplotly(p)

The function mentions to open an issue if such an uncovered geom is used.

Amongst others, I'm trying to use this geom to have tooltips for lines. Since traces show tooltips over the entire length, having a tiny curvature for a line might show the tooltips. I've also created a related Stackoverflow issue.

I'm using #348 to keep track of this issue.

Any updates on this? I am also trying to plot curve but I get the same error

Warning in geom2trace.default(dots[[1L]][[1L]], dots[[2L]][[1L]], dots[[3L]][[1L]]) :
  geom_GeomCurve() 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

thank you
