Draw a Venn diagram given a data frame with the sizes and names of the sets.

Usage

d3Venn(
  sets,
  fill_colors = NULL,
  text_color = NULL,
  center_text = FALSE,
  width = NULL,
  height = NULL
)

Arguments

sets	data.frame, each row correspond to one part in the Venn diagram. Must contain columns sets and size and may contain a column label. Intersections are represented by a list of set names.
fill_colors, text_color	character, vector of colors for filling the circles and the text respectively. Must be interpretable by css (see htmltools::parseCssColors() for allowed formats).
center_text	boolean, should the circles' texts be centered horizontally and vertically?

Examples

# Venn diagram with 2 disjoint sets both of equal size
d3Venn(data.frame(sets = c("A", "B"), size = c(20, 20)))

# Venn diagram with 2 disjoint sets with differnt sizes and labels
d3Venn(data.frame(sets = c("A", "B"), size = c(10, 20), label = c("Set 1", "Set 2")))

# Venn diagram with 2 overlapping sets
d3Venn(data.frame(sets = I(list("A", "B", list("A", "B"))),
                  size = c(10, 10, 2)))

# Venn diagram where B is a subset of A
d3Venn(data.frame(sets = I(list("A", "B", list("A", "B"))),
                  size = c(20, 10, 10)))

# Venn diagram with differnt colors and centered text
d3Venn(data.frame(sets = I(list("A", "B", list("A", "B"))),
                  size = c(20, 20, 10)),
       c("cornflowerblue", "hsl(300, 100%, 70%)"),
       "#FFA500",
       TRUE)
