If you have bzrtools installed you have "bzr graph-ancestry" Which will
generate .png, or .html (which uses a .png and an HTML map).

However it:

1) Always graphs the whole ancestry, which for bzr is 14k revisions
2) This makes the png renderer die if the ancestry is too big
3) Shows all merges, whereas 'bzr viz' uses a different algorithm to
ignore "uninteresting" merges.
4) Can also be used to show 2 ancestries, and will color code based on
what is common, versus what is in left/right and even show the merge base.

It can be useful, the #1 problem is just (1). Having a way to say "bzr
graph-ancestry -r OLD..NEW" would probably make it very useful.
