Ramnath design rCharts wich combine the powerful of open source R and D3.js.
It give very pretty plots. Here is some code, using package XML to collect the data from http://www.sochi2014.com/fr/classement-des-medailles and plot a kind of sankey diagram with rCharts

|Plot with Open source R and rCharts library|
I wrote a piece of code to create a sankey diagram and the result look like we see below
> mm = subset(meltP,select=c(Country, Medal, Count)) > colnames(mm) <- c("target","source","value") > sankeyPlot <- rCharts$new() > #We need to tell R where the Sankey library is. > #I put it as a subdirectory to my current working directory (.) > sankeyPlot$setLib('rCharts_d3_sankey-gh-pages') > #We also need to point to an HTML template page > sankeyPlot$setTemplate(script = "rCharts_d3_sankey-gh-pages/layouts/chart.html") > sankeyPlot$set( + data = mm, + nodeWidth = 15, + nodePadding = 10, + layout = 32, + width = 900, + height = 600 + )
