facet_wrap in treemap

General

Hello!
I'd like to generate a treemap like this one, with the subgroup labels in the black rectangles.

For my treemap I'm using:

ggplot(20CTG_WSC_BP_CC_MF, aes(area = enrichment_ratio, fill = FDR, label = paste(description, overlap, sep = "\n"), subgroup = enrich_cat)) + geom_treemap() + geom_treemap_text(colour = "white", place = "centre", size = 15, reflow = TRUE) + scale_colour_gradientn(colours = "colour") + geom_treemap_subgroup_border(colour = "white", size = 5)

I tried facet_wrap , but it divides my subgroups in 3 parallel blocks

ggplot(20CTG_WSC_BP_CC_MF, aes(area = enrichment_ratio, fill = FDR, label = paste(description, overlap, sep = "\n"), subgroup = enrich_cat)) + geom_treemap() + geom_treemap_text(colour = "white", place = "centre", size = 15, reflow = TRUE) + scale_colour_gradientn(colours = "colour") + geom_treemap_subgroup_border(colour = "white", size = 5) + facet_wrap( ~ enrich_cat)

thanks!
