Here's instructions on playing with the graphs, and source code for the graph layout applet.
New: sources to instrument a C program to generate the graphs shown below
Great big graph pic. And the graph to play with, in .g format as well.
New: X server: fbdev.1000 (95kB; 1086 edges, 943 nodes). You'll have to let it sit a bit for the mess to sort itself out. Also, here is a (somewhat) pre-arranged image (162kB). And here is the histogram.
The other X-server graphs are pretty big, so it may be easiest to view them offline (quick summary). The larger ones are too big for the current array size maximums.. grep for "4000" and change and recompile as necessary.
Simple test program: allocer.8 The source code: allocer.cc
