sankey plot not showing in RPubs

[amandalee1005]

I tried to repopulate timelyportfolio's sankey plot on my machine and publish it. The plot works fine on my machine, but when I publish it to RPubs, the plot is not populated... I've tried to publish other plots, e.g. boxplots built using ggplot2, and they work completely fine.

Here is the code I used:
g <- graph.tree(40, children = 4)
E(g)$weight = 1
edgelist <- get.data.frame(g) #this will give us a data frame with from,to,weight
colnames(edgelist) <- c("source","target","value")

edgelist$source <- as.character(edgelist$source)
edgelist$target <- as.character(edgelist$target)
sankeyPlot2 <- rCharts$new()

sankeyPlot2$setLib('./rCharts_d3_sankey-gh-pages/')

sankeyPlot2$setLib('http://timelyportfolio.github.io/rCharts_d3_sankey/libraries/widgets/d3_sankey')
sankeyPlot2$set(
data = edgelist,
nodeWidth = 15,
nodePadding = 10,
layout = 32,
width = 960,
height = 500
)
sankeyPlot2

sankeyPlot2$publish('sankeyPlot2', host='rpubs')

Look for the htmlwidgets based sankey charts in the NetworkD3 package. @timelyportfolio can help add more information.
