I have a streamgraph similar to this,
library(dplyr)
library(babynames)
library(streamgraph)
babynames %>%
filter(grepl("^Kr", name)) %>%
group_by(year, name)
%>% tally(wt=n) -> baby_names
head(baby_names)
streamgraph(baby_names, "name", "nn", "year")

How can I add a custom tooltip with text coming from other source (e.g., from an additional column of the data frame)
