This example combines a Hilbert jigsaw treemap with an area encoding: Each cell (a class of the flare software package) is scaled accordingly to its size
property. This is different from the standard approach of treemaps, that either uses the leaves' size to affect the whole map, or chooses not to display size information at all (all leaves have a unit area).
