Check out the R graph gallery, a nice resource for various plot types, in your case you're looking for "bubble" plots. But very simply for your data you could do:

library(ggplot2)

df <- data.frame(
  paths = paste0("path",1:3),
  ratio = runif(3),
  count = rnorm(3,200,50),
  p.adjust = runif(3)
)

ggplot(df, aes(x = ratio, y = paths, color = p.adjust, size = count)) + 
  geom_point(stat = 'identity') + 
  xlab("ratio") + ylab("path") + ggtitle("your data") + 
  theme_bw()

that particular figure was likely created by enrichplot, see http://yulab-smu.top/biomedical-knowledge-mining-book/enrichplot.html#dot-plot
