Venn diagram proportional and color shading with semi-transparency

Question

I have following type of count data.

A   450
B   1800
A and B both    230

I want to develop a colorful (possibly semi-transparency at intersections) like the following Venn diagram.

Note: This figure is an example hand drawn in PowerPoint, and it is not to scale.

Answer 1

Here is a post which discusses Venn diagram from list of clusters and co-occurring factors.

For easy solution use package venneuler:

require(venneuler) v <- venneuler(c(A=450, B=1800, "A&B"=230)) plot(v) 

For more advanced and customized solutions check package VennDiagram.

library(VennDiagram)  venn.diagram(list(B = 1:1800, A = 1571:2020), fill = c("lightblue", "green"),               alpha = c(0.5, 0.5), lwd =0, "venn_diagram.tiff") 

Answer 2

I have recently published a new R package, eulerr, which does what you want. It is quite similar to venneuler but without its inconsistencies.

library(eulerr)
fit <- euler(c(A = 450, B = 1800, "A&B" = 230))
plot(fit)

Or you could try the shiny application for the same r package at eulerr.co
