------------------------------------------------------------
There are OmniGraffle files I can send you. I'm thinking it might be better to
transition to plain text "illustrations", i.e.
{code}
data ["foo", "", null, null, "bar2"]
List
----
bitmap 00010011
length: 5
null_count: 2
offsets: 0 3 3 3 3 7
children:
- uint8 (char)
-----
length: 7
null_count: 0
values: f o o b a r 2
{code}
