Hi Sibylle,
I think you want something like barNest (plotrix). It will plot nested 
bars to whatever depth of nesting you want (although I don't think 
anyone would want more than three or four levels), and you can just 
display the final level if you want. I am competely rewriting this 
function at the moment to make it more flexible, and there should be a 
new version of plotrix turning up soon. However, the present function 
will give you an idea of what it will do.
