Performance Clustermap in R

Question

I found this very appealing chart about the performance of the S&P500 from the WSJ.:

I'm trying to recreate it in R but I have no idea how to best plot the data, eg

data<-data.frame(stock=c("A","B","C","D"),group=c(rep("Fin",2),rep("Ind",2)),Perf=rnorm(4,0,1),mvalue=abs(rnorm(4,100,50)))

Has anybody a idea how to recreate it (e.g. with ggplot2?) or has anybody ever done a similar plot? Thx in advance.

Answer 1

treemapify is a ggplot2 solution, as you were hoping for.

And the results are beautiful & flexible - typical of ggplot2 and its extensions.
