Hi,
I renamed all the classes which compose the tree map builder to RO* and they are ready for prime time (i.e., integration in Roassal or Moose).
In addition I provided a ROTreeMapBuilderExample with 10-ish examples on how to use the builder. I should comment the code, but I will do that tomorrow ;) I also committed a specialization of the ROBorder, a ROInnerBorder. As the class name says, it creates the border within the element's shape (i.e., better when lay outing). It's not fully functional, but I already tried out on my tree map and most of the times is ok ;)
Waiting for your feedback and comments.
P.s.: Why if a ROLine is filled with a translucent color its begin and end points are shaded-ish? Here's a screenshot @ https://dl.dropboxusercontent.com/u/6281855/gradient-begin-end.png
Cheers, Roby

Nice! I want this integrated in Roassal, or at least in Moose. Alex?
Would be cool!
About LinearColorNormalizer vs. mix:shades:.
LinearColorNormalizer is better in that it does not create the actual colors. Imagine that you have 2 nodes: one with weight 1 and one with weight 10000. Using mix:shades: you will generate 10000 shades. With LinearColorNormalizer you will generate exactly 2.
Oh, I see. I will probably switch to the color normalizer then!

Hi Doru,
I just added options for shading (on nodes this time) so that you do not have to care about the colors explicitly.
Now we have the messages for:
- #withShadesOnWeightFromColor:toColor: --> Applies the shading on the weight of the node
- #withShadesOnNestingFromColor:toColor: --> Applies the shading on the nesting level of the node
What's the real difference between a LinearColorNormalizer and #mix:shades: I really like #mix:shades: :D
In a minute I will also provide what you said for the shaded frames: #withShadedFrames was an example on how to produce framed tree maps with a single message ;)
Cheers, Roby

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

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 to call #withShadedFrames. How cool is that?
Here's a sample visualization @ https://dl.dropboxusercontent.com/u/6281855/treemap-frames.png
And here's the script:
builder := DFTreeMapBuilder new. builder weightBlock: [ :el | el ]. builder nodes: (1 to: 100). builder nestingFromAssociations: (builder nodes allButFirst collect: [:each | (each // 2) -> each ]).
"Some optional configurations parameters" colors := (Color lightBlue) mix: Color blue shades: (builder nodes size). builder colorBlock: [ :el | colors at: el ]. builder rootColor: (Color red). builder extent: 521@312. builder origin: 20@20.
builder withShadedFrames.
builder draw.
