Distribute R visualization to other users

How can I distribute R visualizations to other users that don't have R?

I have a created a Sankey diagram in R based on the following code (Link), which works great:

library(networkD3)
library(jsonlite)
library(magrittr)
energy <- "http://ift.tt/22Eg0rG" %>% 
  fromJSON
sankeyNetwork(Links = energy$links, 
          Nodes = energy$nodes, 
          Source = "source",
          Target = "target", 
          Value = "value", 
          NodeID = "name",
          units = "TWh", 
          fontSize = 12, 
          nodeWidth = 30)

But, how can I pass this diagram to other users? I was thinking maybe to render it in a web page, but I don't know how.

Any ideas?

Thanks
