  yes -- but you can make one up if you like. e.g.

dd <- expand.grid(drugclass=LETTERS[1:5],

   plant=c("cactus","sequoia","mistletoe")) set.seed(101)
dd$fitvalue <- runif(nrow(dd))

library(ggplot2)
ggplot(dd,aes(x=drugclass,y=plant,colour=fitvalue,size=fitvalue))+   geom_point()

  By the way, I think you could represent your data much more clearly this way: the "Cleveland hierarchy" says that it's easier to assess quantitative values plotted along a common scale than via size or colour ...

ggplot(dd,aes(x=drugclass,y=fitvalue,colour=plant))+   geom_point()+geom_line(aes(group=plant))
