Ok, I took a closer look and you already implemented almost what I said :).
So, let's take a look: withShadedFrames self inset: 1. self strokeAllNodesWithColorBlock: [ :el | Color darkGray darker adjustSaturation: (-0.03 * el depth) brightness: (el depth * 0.08). ].
This is a good start, but: - Color darkGray should not be hardcoded - The actual darkening strategy should not be hardcoded either
I would suggest to use a LinearColorNormalizer instead. This allows you to specify both the min and max color. What do you say?
Cheers, Doru

Nice!
I just do not understand why colors has the same size as the nodes collection. It should have the same size as the max nesting level. What do I get wrong?
In any case, I think for shading we need also strategy that hides the implementation details (so, no explicit color creation). I think that we can just give a min and a max and then simply use a linear color normalizer internally. Of course, we also need a way to marry such an implicit strategy with the possibility of custom colors :). Proposals?

Here is another way to visualize the nesting, with frames. It's enough

Here's a sample visualization @

And here's the script:

builder := DFTreeMapBuilder new. builder weightBlock: [ :el | el ]. builder nodes: (1 to: 100). builder nestingFromAssociations: (builder nodes allButFirst collect:

size).
builder colorBlock: [ :el | colors at: el ]. builder rootColor: (Color red). builder extent: 521@312. builder origin: 20@20.
builder withShadedFrames.
builder draw.

And yes, now the tree map builder does no longer use z-ordering to
lay out the elements ;)
