[R] Visualising multiple temporal periods each with an associated value

Hi Loris,
If I understand what you want, it seems to be a combination of a Gantt
chart and a sizetree. The Gantt chart provides the horizontal extent
of the rectangles and the sizetree the vertical extent by assigning
relative heights to the initial rectangles and dividing these into
subsets as time evolves. That approach would not allow rectangles to
expand over time, but that could be accommodated. It's more
complicated than either of the two, but I think it can be done.
