How to make a sunburst plot in R or Python?

Question

So far I have been unable to find an R library that can create a sunburst plot like those by John Stasko. Anyone knows how to accomplish that in R or Python?

Answer 1

Since jbkunst mentioned ggsunburst, here I post an example for reproducing the sunburst by sirex.

It is not exactly the same because in ggsunburst the angle of a node is equal to the sum of the angles of its children nodes.

# install ggsunburst package
if (!require("ggplot2")) install.packages("ggplot2")
if (!require("rPython")) install.packages("rPython")
install.packages("http://genome.crg.es/~didac/ggsunburst/ggsunburst_0.0.9.tar.gz", repos=NULL, type="source")
library(ggsunburst)

# dataframe
# each row corresponds to a node in the hierarchy
# parent and node are required, the rest are optional attributes
# the attributes correspond to the node, not its parent
df <- read.table(header = T, sep = ",", text = "
parent,node,size,color,dist
,/,,B,1
/,home,,D,1
home,Images, 40,E,1
home,Videos, 20,E,1
home,Documents, 5,E,1
/,usr,,D,1
usr,src,,A,1
src,linux-headers, 4,C,1.5
src,virtualbox, 1,C,1.5
usr,lib, 4,A,1
usr,share, 2,A,1
usr,bin, 1,A,1
usr,local, 1,A,1
usr,include, 1,A,1
")

write.table(df, 'df.csv', sep = ",", row.names = F)

# compute coordinates from dataframe
# "node_attributes" is used to pass the attributes other than "size" and "dist", 
# which are special attributes that alter the dimensions of the nodes
sb <- sunburst_data('df.csv', sep = ",", type = "node_parent", node_attributes = "color")

# plot
sunburst(sb, node_labels = T, node_labels.min = 10, rects.fill.aes = "color") +
  scale_fill_brewer(palette = "Set1", guide = F)
