Graphical tool to show evolution between versions

[avilella]

Hi,

I have a very large text document in a cvs repository that I have been
editing for a long time now.
I am curious to see how it's been changing in content in the ~200
versions I have. Are there any
tool to graphically show the overlap/changes in size/reorderings of
the content of a file between a succession of versions?

Thanks in advance
