Most basic treemap
This is the most basic treemap you can do. The input dataset is simple: we just have 3 groups, and each has a value which we map to an area.
It allows to learn the syntax of the treemap library: you need to provide at least a dataset (data), the column that provides groups (index), and the column that gives the size of each group (vSize).
See graph #235 to learn how to add subgroups, and graph #236 to customize the chart appearance.
# library
library(treemap)
# Create data
group <- c("group-1","group-2","group-3")
value <- c(13,5,22)
data <- data.frame(group,value)
# treemap
treemap(data,
index="group",
vSize="value",
type="index"
)
