[Moose-dev] Mondrian TreeMap Layout

Hi all, I'm playing around with Mondrian and want to use a treemap layout of a graph. I didn't find any examples and tried some things, but could not get the layout to work. At the moment I have something like this: ... view nodes: self nodes. view edges: self nodes from: [ :each | each ] toAll: [ :each | each children ]. view layout: MOTreeMapLayout new. Which produces nothing that makes sense. Could anyone give me some pointers on how to use the MOTreeMapLayout correctly? Thanks, Dennis
