Is it possible to draw a heatmap with circles instead of square in ggplot2? It would be neat to not only represent the values by a color gradient but also by the circle size

    In this example size and colour both correspond with the variable value because it's the only variable numeric available in the kreuz.m dataset.

    ggplot(kreuz.m, aes(Name, variable)) +
      geom_point(aes(size = value, colour=value))
