set.seed(123)
ha1 = HeatmapAnnotation(df = data.frame(type = rep(letters[1:2], 5)))
ha2 = rowAnnotation(point = anno_points(runif(10), which = "row"))
Heatmap(matrix(rnorm(100), 10), name = "mat", km = 2,
    top_annotation = ha1) + ha2
decorate_annotation("type", {
    grid.circle(x = unit(c(0.2, 0.4, 0.6, 0.8), "npc"), 
        gp = gpar(fill = "#FF000080"))
})
decorate_annotation("point", {
    grid.rect(gp = gpar(fill = "#FF000080"))
