The height of the flame in this graph does not seem very informative. In the example, the 3.88% used by the tower of "linux-4.9-rc5/drivers/gpu/drm/amd/include" looks larger than "linux-4.9-rc5/net" over on the right just because the tree is deeper. Similarly, on my Windows machine at work, "C:\Users\LeifCarrotson\AppData\Local\Microsoft\Outlook\Leif@Carrotson.com.pst" (where my email is stored) would take up more screen space than "C:\hiberfil.sys", just because it's taller. I don't much care about the depth of the filesystem. The various tree views seem more useful.
