Hi,
I finished the first version of the new tree map builder for Roassal.
You can find the source code in my SmalltalkHub package 'DevFlow-View'!
Gofer new smalltalkhubUser: 'RobertoMinelli' project: 'DevFlow'; package: 'DevFlow-View'; load.
Here's an example usage:
builder := DFTreeMapBuilder new. builder weightBlock: [ :el | el ]. builder nodes: (1 to: 50). builder associations: (builder nodes allButFirst collect: [:each | (each // 2) -> each ]).
"Some optional configurations parameters" colors := Color white mix: Color blue shades: (builder nodes size). builder colorBlock: [ :el | colors at: el ]. builder rootColor: ((Color red) alpha: 0.5). builder inset: 5. builder extent: 500@300. builder origin: 10@30.
builder draw.
And the resulting tree map!

Please tell me what do you think!
The next steps are: - Add customizable interactions - Remove z-ordering and use proper nesting - Eventually unroll the recursion in the layout algorithm
Cheers, Roberto
