proportional boxes for call time
Consider following screenie:

Weight of "update" and "chunked" relative to each other is represented correctly by block width.
Weight "update" relative to parent is represented wrong, stats show 19%, but box is >50%.
Is that by design? Or only because "own" box is minimum allowed width instead of (100-19-11-3)%?
I cannot answer the question "is that by design". I did not write the visualization. But if you ask me it is one thing that also confuses me.
Either we document the behaviour (there might be a reason for that @fijal ?) or we discuss how it is supposed to be, implement it and document it.
It seems like the size of segments is dictated by the number of children and size of text label for each child. To compensate, color is used to indicate relative percentage time.
