## Three List Venn Diagram

### Description

A function that plots a venn diagram of 3 lists. One point is plotted in each region for each record that falls into the corresponding list overlap.

### Usage

venn3(
overlap.counts,
main = NULL,
num.test.points = 1e+05,
p.cex = 0.75,
write_numbers = FALSE,
t.cex = 1.25,
cex.main = 1
)


### Arguments

 overlap.counts A vector of length 2^3 that gives the number of records in each overlap in lexicographic order, i.e. 001, 010, 011, 100, etc. main the title of the graph num.test.points how many test points to generate as potentials to be plotted in the circles. p.cex the size of the points to be plotted write_numbers indicates whether to print the number of points in each region. t.cex the size of the text to write the numbers. cex.main the size of the title

### Value

a 3-way venn diagram with points inside of each segment representing the number of records on each list overlap.
