Comment(by karsten):

 Replying to [comment:32 karsten]:
 >  - I merged George's patch (thanks!) that outputs degree of anonymity
 instead of plain entropy.  I'll run it shortly and will post the resulting
 graph once I have it.

 Here's the graph showing
 [https://trac.torproject.org/projects/tor/attachment/ticket/6232/degree-
 of-anonymity-2012-07-18.png degree of anonymity].  For reference, it took
 my machine 8:30 hours to compute the entropy values.

 >  - Should we add a second graph that plots entropy and maximum entropy
 as two lines, as Rob suggested above?   That graph should probably consist
 of 2 x 2 sub graphs for the four cases we distinguish.  Should be trivial
 to extend the script to output entropy and max_entropy along with their
 quotient.  I'll look into that and write the graphing code in a bit.

 Here's another graph showing
 [https://trac.torproject.org/projects/tor/attachment/ticket/6232/entropy-2012-07-18.png
 entropy and maximum entropy].

 The remaining comments from above are still valid.  So, we're not done,
 yet.
