Gosper treemap with hierarchical edge bundling

A Gosper treemap of the flare software package hierarchy. Imports, that define links between software classes, are represented using Danny Holten's hierarchical edge bundling (see Holten et al. - 2006).

The tension of the bundling is set to a very high value, to try to give bundles a river-like appearance. Other bundling methods are likely to provide better results at that, like skeleton-based ones (Ersoy et al. 2011).
