  Recent availability of data of writing processes at keystroke-granularity has
enabled research on the evolution of document writing. A natural step is to
develop systems that can actually show this data and make it understandable.
Here we propose a data structure that captures a document's fine-grained
history and an organic visualization that serves as an interface to it. We
evaluate a proof-of-concept implementation of the system through a pilot study
with documents written by students at a public university. Our results are
promising and reveal facets such as general strategies adopted, local edition
density and hierarchical structure of the final text.
