Bible Versions Chart Help

When I say "Help," I'm indicating both that I could use some and that this may be of help to you. I've composed two charts--one for the Bible in general and one for the Psalter in particular--of the history of the versions. It is very approximate, but I'm hoping it gives some sense of the translational activity in antiquity. There certainly is plenty of room for debate on dates (and most developed over extended periods of time) and the relationships between the various versions, but if anyone sees something really wrong, please let me know. Thanks.
