making plotly dendrogram in javascript

Question

Want to make https://plot.ly/python/dendrogram/ with plotly.js. Is it possible? Has anyone implemented dendrogram in javascript?

Do you want to both the figurefactory function and the plot itself? Or do you provide the data and just want to plot it? — Maximilian Peters, Aug 07 '16 at 17:55
data will be provided from external clustering routines and also consumed by a plotly heatmap from plotly.js. — mei, Aug 29 '16 at 17:48

Not exactly answers your question, but in case it helps - you can do it using R combined with the dendextend and plotly packages. Here is a quick example:

install.packages(c("ggplot2", "dendextend", "plotly"))

library(dendextend)
# library(ggdendro)
# Create a complex dend:
dend <- iris[1:30,-5] %>% dist %>% hclust %>% as.dendrogram %>% 
  set("branches_k_color", k=3) %>% set("branches_lwd", c(1.5,1,1.5)) %>% 
  set("branches_lty", c(1,1,3,1,1,2)) %>%  
  set("labels_colors") %>% set("labels_cex", c(.9,1.2)) 
# plot the dend in usual "base" plotting engine:   
# plot(dend)
# Now let's do it in ggplot2 :)
ggd1 <- as.ggdend(dend)
library(ggplot2)
p <- ggplot(ggd1, offset_labels = -.1) # reproducing the above plot in ggplot2 :)

library(plotly)
ggplotly(p) %>% layout(showlegend = FALSE)
