Experimenting with d3
More experimental visualization work (proper query text wrap and containing box sizes)
Construct tree structure from flat data in JS instead of Python
Heat-coloring the branches + other small improvements in tree visualization
Display metrics in the tree
Better (but still imperfect) way do display metrics
Fixed the bug with layout going south after collapsing nodes
Make tree occupy 100% of the available width
Selectable coloring + new screenshot
