A ggplot2 object.

if (FALSE) { # \dontrun{
# Relationship between cell type and cluster
do_SankeyPlot(seurat_obj,
              columns = c("seurat_annotations", "seurat_clusters"))

# Three-way relationship
do_SankeyPlot(seurat_obj,
              columns = c("seurat_annotations", "condition", "Phase"))
} # }
