# Venn Diagram with Proportional Size in R (2 Examples)

This tutorial shows how to draw a venn diagram with proportional size in the R programming language.

The article will consist of two examples for the drawing of venn diagrams. To be more specific, the content of the page is structured as follows:

Let’s get started…

## Example 1: Venn Diagram with Proportional Size Using VennDiagram Package

The following syntax illustrates how to draw a venn diagram with proportional size of the circles using the VennDiagram package.

First, we need to install and load the VennDiagram package:

```install.packages("VennDiagram") # Install & load VennDiagram package library("VennDiagram")```

Now, we can apply the grid.newpage and draw.pairwise.venn functions to create a venn diagram with proportional sizes.

```grid.newpage() # Create new plotting page draw.pairwise.venn(area1 = 10, # Draw pairwise venn diagram area2 = 75, cross.area = 4)``` The output of the previous R code is shown in Figure 1 – A venn diagram with different sizes of the circles.

## Example 2: Venn Diagram with Proportional Size Using venneuler Package

In Example 2, I’ll show how to use the functions of the venneuler package to print a venn diagram with proportional size.

If we want to use the functions of the venneuler package, we first need to install and load venneuler:

```install.packages("venneuler") # Install & load venneuler package library("venneuler")```

Next, we can use the plot and venneuler functions to create a venn diagram:

```plot(venneuler(c(A = 10, # Draw pairwise venn diagram B = 75, "A&B" = 4)))``` In Figure 1 it is shown that we have created a venn diagram with different circle sizes by executing the previous R code.
