Thanks for this PR! But see my comments. Could you also please make this work for non-percentage quantities too?

num <- orig[centers$id[singles | others]]

if (is.null(quantities$labels)) {
type <- quantities$type

if ("percent" %in% type) {
perc <- num/sum(num, na.rm = TRUE)*100
perc <- ifelse(perc >= 1, as.character(round(perc)), "< 1")
perc <- ifelse(perc >= 1, as.character(round(perc,round)), "< 1")# add rounding option to adjust precision of percentage

Can you please use the eulerr_options() interface instead? https://github.com/jolars/eulerr/blob/main/R/eulerr_options.R

I don't think it would be a good idea to add just "round" to the global options. It could easily be overwritten by something else.
