Chord diagram

By Data Tricks, 19 March 2019

A chord diagram is a visual way of displaying inter-relationships between data. Features are arranged in a circle with arcs connecting features which are related.

One of the easiest way to create a chord diagram in R is by using the circlize package.


#Create data
feature=paste("feature ", c(1,1,2,2,2,2,2,3,3,3,3,3,3,3,4,4,4,4,5,5,5,5) , sep="")
dat <- data.frame(name,feature)
dat <- with(dat, table(name, feature))

#Create the circular plot
chordDiagram(, transparency = 0.5)
