One significant problem when building a representation, is to ensure that what it shows is what you think it shows (ha, I just coined my own abbreviation: WISIWYTIS :)). This is particularly important in scenarios in which we take only 15 minutes to look at a piece of data.

If you have nested packing boxes then you should not use the local recomputation of the node size

because you would lose the overall comparison (this is why I say that we should have one that

is neutral) but when you have one

In addition we should be able to pass the parameter from one packing to the other so that

we can pack with smoothing and get the same smooth.

Of course the client that take the responsibility to compute an ecrattype and apply an exponential or a linear

transformation. For my layout are not limited to node positions.

Imagine you have the nodes defining their own size, and at the same time we have the layout that makes a decision about size. Simply by looking at the picture you will not know whether it shows what you expect simply without knowing exactly what decisions have been made by the underlying engine. The only way you will know if by inspecting each shape and see if it matches the node size, and not the implicit sizing algorithm.

I am not sure I made my point clear.

Yes this is why we should pay attention to log and other manipulation.

Now if there is a couple of boxes that fuck up your visualization and as such you

tool and in this turn your end-user and clients then being able to take reasonable actions is important.

In any case, I think we should ensure simple and transparent rules to keep scripts understandable.

I hate the term script. We write programs.

Now if what we are doing is not worth let us know. We can also create our own layouts and do not share them.

I can also avoid to pay guys to work on roassal or to work on our own packages.

Because if having two variability points on packing (which is one difficult algorithm) does not make happy

moosers we will not bother you with that.

but in that case we lose logic. I think that logic should not be in clients. We should have objects that naturally
embed it.

Your approach works but for simple layout. Packing is probably one of the most difficult one
since you have two dimensions and outliers.

As soon as a layout has to change the size of a node, this means that you do not want to use the Mondrian builder, but instead create your own builder. In your case, I think you need to adjust the shape from the script, and not from the layout. For example, Mathieu's code is
