Usage

hc_venn(chart, spec, opts, geom_params, use_js = TRUE, ...)

Arguments

chart	A highchart object (from base_fig() bypass path).
spec	An hd_spec() object. ⁠$data⁠ is unused.
opts	An hd_opts() object.

Highcharts venn series contract

Each entry in sets becomes one element of the Highcharts data array:

• Single set: list(sets = list("A"), name = "Animals", value = 5)

• Intersection: list(sets = list("A", "B"), value = 2)

name is optional for intersections but required for single sets if you want a label in the diagram.
