This is an interesting exercise.  I see at as an application of
a Likert plot.  I would start with this

tmp <- data.frame(x = c(0.1,0.6,0.2,0.1),
                  y = c(0.5,0.2,0.2,0.1))


tmp$xx <- 1
tmp$yy <- tmp$x / tmp$y
tmp$xy <- tmp$xx * tmp$x
tmp$xxx <- tmp$xx - tmp$xy
tmp$yyy <- tmp$yy - tmp$xy
tmp

## install.packages(HH)  ## if necessaruy
require(HH)
likert(tmp[, c("xxx","xy","yyy")],
       xlab="scaled to xxx+xy = 1",
       sub="xxx+xy = 1, xy/(xxx+xy) = x, xy/(xy+yyy) = y")


My guess is that this graph would be more meaningful if it were scaled to
counts rather than to xxx + xy = 1.
