Empty plot when trying to customize nodes colors with version 0.3

[sebastien-foulle]

Hi,

with networkD3 0.2.13 the following minimal example plots a gold box, and with version 0.3 the plot is empty :

Links = data.frame(Source = 0, Target = 0, Value = 1)
Nodes = data.frame(name = "a")

library("networkD3")

sankeyNetwork(Links, 
              Nodes, 
              Source = "Source",
              Target = "Target", 
              Value = "Value", 
              NodeID = "name",
              colourScale = JS("d3.scale.category20().range(['gold'])")
)

sessionInfo()

We have updated networkD3 to D3v4, which has some significant changes. You will need to change your colourScale argument to...

colourScale = JS("d3.scaleOrdinal(d3.schemeCategory20).range(['gold']);")

also, check the help file for working examples (and the new default value for colourScale)
