So, I'm working on tools (in 'R', my faaaavorite visualization
environment) to help me understand the impact of a new
collocation-group calculation tool.  I'm reaching for some concise
visual idiom which will help me see trouble spots.

What I've arrived at so far is a column for each volume, with the left
hand side illustrating collocation-group occupation on the volume, and
the right hand side illustrating node occupation.

This method has some limitations (*koff*)

but I think I can make that graph somewhat more clear by excluding
from consideration the "Obviously good" volumes; defined as those
which are totally occupied by either one node, or one collocation
group.


But I'm looking for inspiration on how to visualize "A volume", and "A
collocation group".

It seems to me that those are the most productive perspectives: If you
find "A group" with a lot of intrusion, that suggests a place to start
fixing.  If you find "A volume" with many groups/nodes, that's a good
candidate for twiddling.

Any ideas?


I considered trying to come up with cute little tape outlines, and
using the tape outlines to crop pie-charts populated by-group and
by-node, but I was afraid that Edward Tufte would come to my house and
kick me really really hard.
