I don't have any plans to make a geom_treemap_interactive, but you can get a pretty decent approximation by drawing a geom_rect_interactive overlay with manually calculated treemap coordinates:
library(treemapify)
library(ggiraph)
library(ggfittext)
library(tidyverse)
# Manually build treemap layout
treemap <- treemapify(G20, area = "gdp_mil_usd")
treemap <- left_join(treemap, G20)
# Build ggplot2 treemap object
plot <- ggplot(treemap, aes(
area = gdp_mil_usd,
fill = region,
xmin = xmin,
xmax = xmax,
ymin = ymin,
ymax = ymax,
tooltip = country,
label = country
)) +
geom_treemap() +
geom_treemap_text() +
geom_rect_interactive(alpha = 0.1) +
# Remove plot elements added by geom_rect_interactive
scale_x_continuous(expand = c(0, 0)) +
scale_y_continuous(expand = c(0, 0)) +
theme(axis.text = element_blank(), axis.ticks = element_blank())
# Draw with ggiraph
ggiraph(code = print(plot))
I've seen tooltips in ggiraph, but have had no luck to enable html tool tips for a hover over. Is it supported by treemapify or are there other approaches?
